摘要

利用熔铸 -原位反应和压铸成形技术制备了TiC/AlSi9Cu1.4Mg0 .5复合材料

测试了复合材料的力学性能。结果表明 :TiC/AlSi9Cu1.4Mg0 .5复合材料的室温抗拉强度为 3 5 4MPa

比基体合金提高 2 6% ;2 60℃时复合材料的抗拉强度为2 72MPa

比基体合金提高 46%。复合材料的伸长率与AlSi9Cu1.4Mg0 .5合金相当

Abstract

The die-casting TiC/AlSi9Cu1.4Mg0.5 composite has been prepared successfully by both smelting in-situ reaction and die casting tec hnique. The mechanical properties of the composites were measured. The results showed that t he ultimate tensile strength of the die casting TiC/AlSi9Cu1.4Mg0.5 composites w ith 354 MPa at room temperature and 272 MPa at 260 ℃

are higher by 26% and 46% than those of the matrix alloy（280 MPa and 186 MPa）respec ti vely. The elongation of the die casting composite at room temperature and 260 ℃ are comparable to those of the conventional AlSi9Cu 1.4Mg0.5 alloy.
