## Description

- description: To clarify the effect of pores on high temperature compressive behavior
    due to kink deformation, textured Ti3SiC2 pressureless sintered bodies were fabricated
    and examined by high temperature compression tests with different porosities.
    The textured Ti3SiC2 pressureless sintered bodies were prepared by slip casting
    in a strong magnetic field and spark plasma sintering at 1400℃ for 1 h. Samples
    were cut into rectangular shape with 45° between the casting direction and the
    compression axis, and compression tests were conducted at 1200℃ at a strain rate
    of 3 × 10-4 s-1.　Porosity was evaluated by Archimedes method and binarization.
    Crystal orientation analysis using EBSD method was performed to observe the microstructure
    evolution before and after the compression test. The sintered bodies had a strongly
    textured microstructure with homogeneous dispersed pores. The results of high
    temperature compression tests showed that the 0.2% proof stress depended on the
    porosity before compression tests. On the other hand, the work hardening coefficient
    was larger for plessureless sintered sample with high porosity, which attributed
    to the densification associated with the compression. Microstructural observations
    indicated that fine kink bands formed in the middle stage of the compression and
    then disappeared, suggesting that this is important for clarifying kink-band strengthening
    in the MAX phase.
