摘要
本文研究了用常规粉末冶金工艺制备颗粒增强铜基热沉复合材料的机械物理性能。研究结果表明 :采用W和Al2 O3颗粒增强铜基热沉复合材料 ,可以有效地改善烧结铜材料的硬度和抗拉强度 ,提高抗高温回复性能 ;W颗粒增强铜基热沉复合材料比Al2
The mechanical and physical properties of particles reinforced copper matrix composites for heat sinks produced by powder metallurgy are studied here. It shows that the addictives of tungsten and Al 2O 3 particles can effectively improve copper matrix composites' hardness, tensile strength and recovery crystallizing temperature. Copper matrix composites for heat sinks reinforced with tungsten particles have better thermal conductivity than those reinforced with Al 2O 3 particles.
