摘要
采用冷拔变形结合中间热处理制备了形变Cu-15Fe-0.15Zr和Cu-15Fe-0.15Zr-2Ag原位复合材料。用SEM、精密万能试验机和电阻测量仪研究了Ag元素对形变Cu-Fe-Zr原位复合材料组织、抗拉强度和导电性能的影响。微观组织观察结果表明:Ag元素的加入对合金微观组织未产生明显的影响;随变形量的增大,Fe纤维逐渐变细变均匀。抗拉强度和电导率测试结果表明,Ag元素的加入能明显提高合金的强度和电导率。当应变量达到6.7,两种合金的强度分别达到1197 MPa和1338 MPa,电导率分别为64%IACS和71%IACS。
The Cu-15Fe-0.15Zr and Cu-15Fe-0.15Zr-2Ag in-situ composites were prepared using cool-drawing deformation combined with intermediate heat treatment. The effect of element Ag on the microstrueture, tensile strength and electrical properties of deformation-processed Cu-Fe-Zr in-suit composites were investigated by SEM, precision universal testing machine and resistance meter. SEM analysis shows that： the microstructures were not change obvious, and the Fe fibers are turned finer and more uniform along with the deformation increase. The testing of tensile strength and electrical conductivity results showed that the presence of element Ag can improve both the strength and electrical conductivity. It can obtain the tensile strength 1 197 MPa and 1 338 MPa, electrical conductivity 64%IACS and 71%IACS at strain η=6.7.
