中文摘要：
采用冷变形＋适当的中间热处理的方法制备了Cu-15Cr-0.2Zr形变原位复合材料，并研究了微量盈对Cu-15Cr原位复合材料组织和性能的影响。结果表明：合金经室温变形后，Cr相转变成弯曲薄片状纤维，随着应变量的增加，合金的强度提高，导电率下降。添加0．2％盈使Cu-15Cr-0.2Zr在η=6．438时的极限抗拉强度达到1072MPa，导电率达到68.7％IACS。
英文摘要：
Effect of Zr on microstructure and property of deformation processed Cu-15Cr-0.2Zr in situ composites obtained by cold drawing with appropriate intermediate heat treatments was investigated. The results indicated that after the alloys were drawn to various strains at room temperature, the Cr phase were drawn into fine ribbons. The tensile strength can be increased and the electrical conductivity can be decreased with the increasing of strain. When stain η=6.438, with the addition of 0.2%Zr the ultimate tensile strength of Cu-15Cr-0.2Zr reached 1072MPa and the electrical conductivity reached 68.7%IACS.
