China 2) Sinoma International Engineering CO.,Ltd.(Nanjing),106 Jiangjun avenue, Nanjing Jiangsu 211100, China The ZrB2/SiC/Zr2Al4C5 multi-phase ceramics were fabricated by spark plasma sintering (SPS) at 1800℃ for 3 min under 20 MPa in an vacuum. Oxidation behavior of multi-phase ceramics were investigated using thermo gravimetric analysis (TGA) from 20℃ to 1500℃ and muffle furnace in stagnant air at 1200℃. Samples were analyzed after oxidation by X-ray diffraction (XRD), scanning electron microscopy (SEM) along with energy dispersive spectroscopy (EDS) to determine the reaction products and to observe the microstructure. The results showed that the aluminium borate and mullite crystallize on the surface in the samples oxidized.

Experimental results show that surface crystal size was refined to 52.8nm after SMAT for 15min. A 20μm thick nanocrystalline layer, with gradient changing crystal size from dozens of nm in the surface to 200~500nm deep into the substrate, was successfully obtained. The microarc oxidation ceramic coating with 5μm thickness grew by consuming part of the nanocrystalline layer. Since the local heat produced in the microarc discharge channels was not enough to lead to the growth of the substrate grain, the alloy substrate near to the coating/substrate interface still maintained a nano-grained size. Therefore SMAT-MAO coating, which consists of an outer ceramic coating and an inner nanocrystalline layer, was obtained.

The ATO thin films are prepared by pulsed laser deposition method with high quality, namely the sheet resistance of 49.5 Ω/sq and average transmittance of 81.9 %. The prepared graphene sheet is well reduced and shows atomically thin, spotty distributed appearance on the top of the ATO thin films. The XRD and optical micrographs are used to confirm the successfully preparation of the ATO/graphene multi-layered thin films. The Hall measurements and UV-Vis spectrophotometer are conducted to evaluate the sheet resistance and optical transmittance of the innovative structure. It is found that graphene can improve the electrical properties of the ATO thin films with little influence on the optical transmittance.

The raw materials were tetraethyl orthosilicate (TEOS), etoh ehanol (EtOH), iron nitrate, and de-ionized water. Various properties were measured and analysed, including the colour of thin films, surface topography, UV-Visible spectra, corrosion resistance and hydrophobicity. To understand how these properties influenced the structural and optical properties of Fe2O3 thin films, Scanning Electron Microscope (SEM), UV Spectrophotometer and other facilities were employed. Many parameters influence the performance of thin films, such as film layers, added H2O content, and the amount of polydimethylsiloxane (PDMS). When the volume ratio of TEOS, EtOH and H2O was 15: 13: 1, the quality of Fe(NO3)3・9H2O was 6g, and pH value was 3, reddish and uniform Fe2O3 thin films with excellent properties were produced. Obtained thin films possessed corrosion resistance in hydrochloric acid with pH=1 and the absorption edge wavelength was ~350.2nm. Different H2O contents could result in different morphologies of Fe2O3 nanoparticles. When 1.5 ml PDMS was added into the Sol, thin films possessed hydrophobility without dropping. Coating with different layers, thin films appeared different morphologies. Meanwhile, with the increment of film layers, the absorbance increased gradually.

Deformation at high strain rates was carried out by using a ball-dropping test, while deformation at low strain rates was performed by a ball-pressing test on a computer controlled servohydraulic machine. Evaluation of the local plastic strain was conducted by using the electron backscatter diffraction (EBSD) analysis. Experimental evidences indicate that high strains with high strain rates lead to large gradients of the plastic strain distribution profile and also a localized severe deformation near the surface. Furthermore, deformation at high strain rates is favourable to impose plastic deformation at the selected area near the sur face.

China Thermal-mechanical analysis is performed on W/CuCrZr plasma facing component with functionally graded material (FGM) interlayer under the steady-state heat load of 5 MW/m2 using a finite element method (ANSYS code). The influences of the FGM interlayer on the stress, strain and temperature distribution in the whole component is evaluated and compared to the joint without an interlayer and with OFHC interlayer. It is shown that the inserting of W/CuCrZr FGM interlayer between W and CuCrZr effectively alleviates the thermal stress, whose reduction can reach up to 70% when the W/CuCrZr FGM interlayer thickness exceeds 6 mm. Meanwhile, the optimization of the structure and component distribution for W/CuCrZr FGM interlayer was also carried out. The thermal stress tends to saturate with the layer number exceeding 4. For 6 mm 4-layered FGM interlayer, the preferred component distribution exponent (p) is 1.8.

Nanometer sized alumina particles were dispersed into acrylic liquid resins, and the obtained slurries were sputtered by using compressed air jet. The slurry mists could blow into the arc plasma with argon gas spraying. On stainless steels substrates, the fine surface layers with high wear resistance were formed. In cross sectional microstructures of the coated layers, micromater sized cracks or pores were not observed. Subsequently, pure aluminum particles were dispersed into photo solidified acrylic resins, and the slurry was spread on the stainless steel substrates by using a mechanical knife blade. On the substrates, microline patterns with self similar fractal structures were drawn and fixed by using scanning of an ultra violet laser beam. The patterned pure metal particles were heated by the argon arc plasma spray assisting, and the intermetallics or alloys phases with high hardness were created through reaction diffusions.

China Strain gradient theories have been considered to be an effective means for capturing the size effects on ceramic particle-reinforced metal-matrix composites (MMCp), but the results predicted by them are significantly lower than the corresponding experimental data. One reason might be, that the thermal residual stresses caused by thermal contraction mismatch between the metal matrix and the ceramic particle were neglected in the numerical models. By incorporating the Taylor-based nonlocal theory (TNT) of plasticity, the finite element method (FEM) is applied in the present research, to investigate the effect of thermal residual stresses on the yield stress and average axial stresses of the aluminium matrix reinforced by silicon carbide particles (SiCp/Al). The elements of the matrix have been implemented in the ABAQUS finite element code through its USER-ELEMENT (UEL) interface for TNT plasticity. Some comparisons with the associated literature demonstrate that the numerical model with the thermal residual stresses is more in agreement with the experimental results.

China The stress increments depend not only on the plastic strain but also on the gradient of plastic strain, when the characteristic length scale associated with non-uniform plastic deformation is on the order of microns. In the present research, the Taylor-based nonlocal theory of plasticity (TNT plasticity), with considering both geometrically necessary dislocations and statistically stored dislocations, is applied to investigated the effect of particle shapes on the strain gradient and mechanical properties of SiC particle reinforced aluminum composites(SiC/Al composites). Based on this theory, a two-dimensional axial symmetry cell model is built in the ABAQUS finite element code through its USER-ELEMENT (UEL) interface. Some comparisons with the classical plastic theory demonstrate that the effective stress predicted by TNT plasticity is obviously higher than that predicted by classical plastic theory. The results also demonstrate that the irregular particles cause higher effective gradient strain which is attributed to the fact that angular shape particles give more geometrically.

Ceramic materials are frequently used in protective armor applications for its low-density, high elastic modulus and high strength. It may be subject to different ballistic impacts in many situations, thus many studies have been carried out to explore the approach to improve the mechanical properties of the ceramic material. However, the materials manufactured in real world are full of defects, which would involve in variable fractures or damage. Therefore, the defects should be taken into account while the simulations are performed. In this paper, the dynamic properties of ceramic materials (Al2O3) affected by different strain rate (500-5000) and porosity (below 5%) are investigated. Foremost, the effect of strain rate was studied by using different load velocities. Then, compression simulations are performed by setting different porosities and random distribution of pores size and location in ceramic materials. Crack extensions and failure modes are observed to describe the dynamic mechanical behavior.

China The development of Functionally Graded Materials (FGM) for energy-absorbing applications requires understanding of stress wave propagation in these structures in order to optimize their resistance to failure. One-dimensional stress wave in FGM composites under elastic and plastic wave loading have been investigated. The stress distributions through the thickness and stress status have been analyzed and some comparisons have been done with the materials of sharp interfaces (two-layered material). The results demonstrate that the gradient structure design greatly decreases the severity of the stress concentrations at the interfaces and there are no clear differences in stress distribution in FGM composites under elastic and plastic wave loading.1. IntroductionEarly composite targets were made by simply bonding a ceramic tile to a metal backing plate. The underlying idea is to use the hard ceramic layer to defeat and erode the projectile, and to use the backing plate to absorb the impact energy and increase the fracture resistance of the target. The full potential of ceramic hard facing layers has not been achieved because the interface between ceramic and metal has an unfavorable impedance mismatch that may even induce tensile failure. At present, functionally graded materials (FGM) was introduced to armor structure design. The advantage of using FGM is their superior resistance to interfacial failure. Analytical and computational studies of the evolution of stresses and displacements in FGM show that the utilization and optimization of structures and geometry of a graded interface between two dissimilar layers can reduce stresses significantly. The emergence of functionally graded materials (FGM) provides a possible avenue for solving this problem since an FGM layer between the ceramic and metal can make the impedance change continuous rather than abrupt. FGM materials could, therefore, reduce the intensity of reflected 4Corresponding author, Tel.: +86 27 87651820; Fax: +86 27 87860863 E-mail: liulish@whut.edu.cn (L S Liu) FGM 2012 IOP Publishing Journal ofPhysics:ConferenceSeries 419 (2013) 012046 doi:10.1088/1742-6596/419/1/012046 Published underlicencebyIOPPublishingLtd English Journal of Physics: Conference Series Journal of Physics: Conference Series Vol. 419, 2013 2013-03-28 012047 Synthesis and characterization of Dopamine graft compound N-methacryloyl 3,4-dihydroxyl-phenylamine Synthesis and characterization of Dopamine graft compound N-methacryloyl 3,4-dihydroxyl-phenylamine Xiong Xiong 1),2), Qu Shu-xin 2), Liu Yu-mei 2)1) Southwest Jiaotong University-emei, Emei 614202;2) School of Material Science and Engineering, Key Lab of Advanced Technologies of Materials, Ministry of Education, Southwest Jiaotong University, Cheng du 610031 Xiong Xiong 1),2), Qu Shu-xin 2), Liu Yu-mei 2)1) Southwest Jiaotong University-emei, Emei 614202;2) School of Material Science and Engineering, Key Lab of Advanced Technologies of Materials, Ministry of Education, Southwest Jiaotong University, Cheng du 610031 In order to obtain adhesive biomaterials inspired by mussels, the intermediate de-rivatives of dopamine, N-methacryloyl 3,4-dihydroxyl-phenylamine (dopamine methacryla-mide DMA), was synthesized by grafting methacrylate anhydride to dopamine.

China In this article, mechanical properties of nanocrystalline Al+α-Al2O3 composites are investigated using molecular dynamics simulations. The configurations of matrix and volume fraction of α-Al2O3 may affect the mechanical properties of the particle reinforced metal-matrix composites and are taken into account. The potentials for the Al+α-Al2O3 system developed by Xin Lai et al. are adopted to depict the interactions between Al and α-Al2O3. Monocrystal Al and Bicrystal Al based α-Al2O3 particle reinforced nanocomposites are modelled respectively. Results show that: (1) volume fraction of the particles has no explicit effects on the elastic modulus and ultimate strength in both monocrystal Al and bicrystal Al based matrix nanocomposites, (2) disappearance of valley in the stress-strain curve of bicrystal Al results from existence of dislocation in matrix of various orientations.

The present work was conducted with a motivation to develop composite materials with a positive temperature dependence of thermal conductivity. ZrO2/ stainless steel powders (304L) composite, with 3% stearic acid, was prepared by normal sintering under the protecting of Ar after mixing by mechanical ball milling technique. With the 304L content increasing from 10% to 20%, the thermal conductivity values increased. For all samples, the thermal conductivity in the temperature range of room temperature to 700 ℃ decreased with temperature below 300 ℃, and then began to increase. The increasing thermal conductivity of the composites (within the high temperature range was attributed to the difference of the thermal conductivity and thermal expansion coefficient between ZrO2 ceramic and 304L stainless steel powders. Two simple models were also used to estimate the thermal conductivity of the composites, which were in good agreement with the experiment results.

Functionally graded material (FGM) seems to be an effective method to improve the adhesive strength of thick W coating. This paper focused on the finite element simulation on thermal stress for W/Cu FGM with different graded layers, composition and thicknesses. In addition, the variance of stresses for functionally graded coatings with the steady state heat flux were simulated by finite element analysis (ANSYS Workbench). The results showed that the W/Cu FGM was effectively beneficial for the stress relief of W coating. Meanwhile, the maximum von mises stress decreased approximately by 52.8 % compared to monolithic W plasma facing material. And the four-layer FGM with a compositional exponent of 2 was optimum for 1.5 mmWcoating.

The compositions of the mixed powders are Fe-18Cr-8Ni-2W-1Ti-0.35Y2O3. The effects of milling time on nitrogen absorption were investigated. The nitrogen contents in the as-milled powders reached 0.31 wt% after milling for 60 hours and nearly 0.8 wt% after milling for 150 hours. The as-milled powders were then annealed under vacuum at 1173K and 1373 K to promote the formation of the resultant equilibrium phases. Fully austenitic structure was achieved after annealing at 1173K.

China In the paper, we used the LS-DYNA FE code to simulate the bullet penetration against the target plate with different ceramic-steel ratio of thickness. The main stages of the bullet penetration and damage contours of the target were studied by analyzing the residual velocity-time curves. We also studied energy absorption of the ceramic/metal target. Considering curves of residual velocity-time, we reckon the process of penetration contains four stages. Ceramic performed good resistance before the formation of damage cone of ceramic. But after the damage cone formed, the anti-penetration behavior kept declining. When the bullet started to penetrate the layer of metal, the anti-penetration behavior of target rose slightly. Compared with thickness ratio of 0.4 and 0.6, ceramic with 0.2 absorbed more energy and works longer. Of several different thicknesses, layers of ceramic and steel were studied. Steel per cm absorbed more energy than ceramic per cm.

The attenuation properties of stress wave propagation along the SiC3D/Al composite are studied by a Split Hopkinson Pressure Bar system & FEM simulations, and the attenuation mechanism is discussed in this paper. Results show that the attenuation rate of the stress wave in the composite is up to 1.73MPa・mm-1. The reduction of the amplitude of waves is caused by that plenty of interfaces between SiC and Al within the composite acting with stress waves. When the incident plane wave reaches theSiC3D/Al interface, reflection wave and transmission wave propagates in different directions along the irregular interface between SiC phase and aluminium phase due to the impedance mismatch of them, which leads to the divergence of stress wave. At the same time, some stress micro-focuses occurs in the aluminium phase for the complex wave superimposition, and some plastic deformation may take place within such micro-regions, which results in the consumption of stress wave energy. In conclusion, the stress wave attenuation is derived from divergence and consumption of stress wave.

Shaanxi University of Science & Technology, Xi’an Shaanxi, 710021, PR China Gradient nano-TiO2(anatase) /tourmaline beads were prepared by sol impregnated method，and the phase composition and microstructure of gradient coating were characterized by XRD and SEM, and the photocatalytic activity were evaluated by degradation of methyl orange(MO), compared with that of pure nano-TiO2 (anatase), tourmaline beads. The result indicated that the MO degradation ratio by tourmaline beads is 5.8%; that by pure nano-TiO2 (anatase) is 38.2%; while the MO degradation ratio approached 70.4% by gradient nano-TiO2 (anatase) /tourmaline beads, much better than the other two types of catalysts. When the gradient nano-TiO2 (anatase) /tourmaline beads are illuminated by UV irradiation, the electron-hole pairs are generated and the photogenerated carrier will be adsorbed tightly on the anode of tourmaline, owing to its strong electrostatic field, which suppresses the recombination of the electron-hole pairs, and enhances photocatalytic efficiency.
