| 摘 要： | 采用粉末冶金的方法在1000℃和30MPa的热压条件下，烧结制备了以Ti3AlC2为增强相的Ti3AlC2／Cu复合材料，研究了增强相含量（10％～40％）对复合材料的显微结构、抗弯强度、硬度和电阻率的影响。结果表明：Ti3AlC2能够有效增强铜，当Ti3AlC2含量为30％时，增强效果最佳，复合材料的抗弯强度达1033MPa，最大形变为2．5％，增强相含量继续增加时，复合材料的强度反而降低；随着增强相含量的增加，复合材料渐趋脆性断裂，同时复合材料的电阻率基本呈线性升高。

| Abstract: | Ti3AlC2/Cu composites with different volume percent of Ti3AlC2 were prepared by HPS, and the effect of Ti3AlC2 content on the microstructure, hardness, electrical resistivity and flexural strength of the composites were investigated. The result demonstrates that Ti3AlC2 is an effective reinforcement for Cu. The highest flexural strength of the composites was 1033 MPa with the strain of 2.5% when the Ti3AlC2 content was 30%, the fracture in mode was changed from ductile to brittle with the increase of Ti3AlC2 content, while the room temperature electrical resistivity of the composites was increased linearly. |
