Orientation Dependence of Plastic Deformation Behavior and Fracture Energy Absorption Mechanism around Vickers Indentation of Textured Ti<sub>3</sub>SiC<sub>2</sub> Sintered Body

In order to clarify plastic deformation behavior and mechanism of fracture energy absorption Ti3SiC2, Vickers indentation tests were conducted for Ti3SiC2 sintered bodies with various textured orientations. Textured fabricated by slip casting in a strong magnetic field spark plasma sintering (SPS), their orientation distribution analyzed SEM/EBSD. It was found that the around indents such as an indent shape grain pile-up strongly affected basal kink deformation. Furthermore, also depended on texture From our results, it is concluded most effective factor suppressing crack propagation pile-up, second one deflections.
