中文摘要：
采用大气熔铸与形变原位复合的方法制备了Cu-15％Cr形变原位复合材料，测定了不同应变量和中间热处理温度下的显微硬度、抗拉强度和电导率。并研究了Cu-15％Cr原位复合材料的显微组织。结果表明，大气熔铸与真空熔铸制备的Cu-15％Cr复合材料铸态组织没有明显差别；通过改变应变量以及调整中间热处理，可以获得不同的显微硬度、强度和电导率的组合；中间热处理温度在480℃以下，可以获得抗拉强度〉1000MPa、电导率〉71％IACS的Cu-15％Cr形变原位复合材料。其综合性能与真空熔铸制备的形变Cu-15％Cr原位复合材料相当。
英文摘要：
Cu-15%Cr in-situ deformation composite was prepared using melting and forging in air and the in-situ production technique, the mircrohardness, tensile strength and electrical conductivity under different strain capacity and different intermediate heat treatment temperature were tested, and the microstruture of Cu-15%Cr in-situ deformation composite was studied. The results show that there isn＇t obvious distinction between the as-cast structure of Cu-15%Cr composite prepared by melting-forging in air and in vacuum; Cu-15%Cr composite which have different combination of mircrohardness, strength and electrical conductivity can be obtained through controlling swain capacity and adjusting intermediate heat treatment; while intermediate heat treatment temperature is below 480℃ , Cu-15% Cr in-situ deformation composite can be obtained with tensile strength 〉1 000MPa and electrical conductivity 〉71%IACS.Its synthetic properties are similar to the composite prepared by melting-forging in vacuum.
