Abstract： Influence of different extrusion pressures and pouring temperatures on comprehensive performance of (Al63Cu25Fe12)p/ZL101 composites is studied in this paper. The results show that the tensile strength, elongation and hardness of (Al63Cu25Fe12)p/ZL101 composite increase with the squeezing pressure increasing from 50 MPa to 100 MPa, and gradually reduce from 100 MPa to 150 MPa. In addition, the mechanical properties of the composite can be improved with pouring temperature growing, while the temperature should not exceed 760 ℃. When squeezing pressure is 100 MPa and pouring temperature is 720 ℃, mechanical properties of composites are the best. Finally, the mechanical properties of (Al63Cu25Fe12)p/ZL101 composite will be improved by suitable heat treatment technology.

摘 要: 研究了挤压压力和浇注温度对(Al63Cu25Fe12)p/ZL101复合材料性能的影响。 结果表明： 当挤压压力为50-100 MPa时， 复合材料的抗拉强度、 伸长率和硬度会随着压力的增加而增大， 然而当挤压压力为100-150 MPa时， 随着压力的升高， 其综合力学性能会随之下降。 此外， 复合材料的力学性能会随着浇注温度的升高而提高， 但温度不能超过760 ℃。 当挤压压力为100 MPa， 浇注温度为720 ℃时， 复合材料的综合力学性能最优。 最后， 选择合适的热处理工艺来进一步提高复合材料的力学性能。
