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 technique. The mechanical properties of the composites were measured. The results showed that the ultimate tensile strength of the die casting TiC/AlSi9Cu1.4Mg0.5 composites with 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）respectively. The elongation of the die casting composite at room temperature and 260 ℃ are comparable to those of the conventional AlSi9Cu 1.4Mg0.5 alloy.
