Alternative title: Three-Dimensionally Gradient and Periodic Harmonic Structure for High Performance Advanced Structural Materials

Description:

Creation of a unique “Harmonic Structure (HS)” with controlled bimodal grain size
distribution in metals and alloys is a new material design paradigm allowing the improved mechanical performance of structural materials via enhancing strength without sacrificing ductility. A well designed powder metallurgy based processing approach has been developed to create such a controlled microstructure which consists of controlled mechanical milling (MM) of powder particles to create powder particles with bimodal grain size distribution, with a peculiar core-shell structure, followed by their hot consolidation. In the present study, full density compacts with HS
were prepared and the effect of such a bimodal microstructure on the mechanical properties of commercially pure Ti was investigated. The h
