摘要

通过XRD、OM、SEM、TEM和拉伸试验等手段

研究了不同Fe

Al含量和变形工艺对原位自生Fe

Al增强Cu基复合材料显微组织和力学性能的影响。结果表明

当Fe

Al含量增加时

复合材料晶粒明显细化;第二相以纳米尺度的Fe

Al为主

且均匀分布在Cu基体中;经过冷轧和退火处理后

晶粒进一步细化

同时强度得到提升。Fe和Al含量分别为10%的复合材料在经过90%冷轧变形和350℃×1h退火处理后

显微硬度（HV）和抗拉强度分别达到272和871MPa。

Abstract

The effects of Fe

Al reinforced particles and deformation technology on microstructures and mechanical properties of the Fe

Al/Cu composites fabricated by in-situ reaction were investigated by XRD

SEM

TEM and tensile testing.The results show that with the increase of Fe

Al contents

the grain size is decreased.The nanoscale Fe

Al particles are uniformly distributed in Cu matrix.After cold rolling and annealing

obvious grain refinement and significant increment in strength are observed.After 90%cold-rolling reduction

the hardness and strength of 10% Fe

Al/Cu composite containing 10% Fe and Al elements reach 272 HV and 871 MPa

respectively.
