Effect of Ti3SiC2 Content on Mechanical Properties of Ti5Si3-TiC-Ti3SiC2 Composites

Chao Qin, Lianjun Wang, Sheng Qiang Bai, Wan Jiang, Lidong Chen

Abstract

Ti5Si3-TiC-Ti3SiC2 composites containing different Ti3SiC2 volume fractions from 0 to 50% were in-situ fabricated by spark plasma sintering using Ti and SiC powders through adjusting the molar ratio of Ti to SiC. The morphologies of the fracture surfaces were analyzed by scanning electron microscopy (SEM). The room temperature mechanical properties of composites including hardness, bending strength and fracture toughness were tested.
