“…6,7) Besides, it is well known that Ti 3 SiC 2 is a typical MAX phase, which possesses the advantages of both metals and ceramics, such as low density (4.5 g·cm ), high strength and modulus (340 GPa), good thermal and electrical conductivity, damage tolerance at room temperature and excellent resistance to oxidation up to 1173 K. [8][9][10][11] However, the application of Ti 3 SiC 2 was limited because of its poor wear resistance and low hardness. 12) Many studies have been conducted to improve the hardness and wear resistance of Ti 3 SiC 2 , [13][14][15] and it was found that Ti 5 Si 3 can be used as reinforce particles for Ti 3 SiC 2 due to their similar thermal expansion coef cients.…”
