摘要
通过分道次冷轧和多次中间退火工艺制备了Cu-10Fe-2Ag-0.15Zr原位复合材料,并对其组织、强度、电导率和形变量之间的关系进行了研究。研究表明形变量越大,Fe纤维越均匀细化,强度越高。中间退火可以在不损害其强度的情况下大幅提高其电导率。通过变形和中间退火的合理配合,可获得较好强度和电导率匹配。本实验较好的强度和电导率组合为820MPa/55.4%IACS和713MPa/61.3%IACS。
Deformation-processed Cu-10Fe-2Ag-0.15Zr in-situ composites were produced by several cold rolling processing and intermediate annealing.The relations between the microstructure,tensile strength,electrical conductivity and the strains were studied.The strain is higher,Fe fiber becomes thinner and the tensile strength is higher.The tensile strength is hardly decreased in intermediate annealing and the electrical conductivity was improved.Good combinations of the tensile strength and electrical conductivity are achieved.In this paper,the better combinations of the tensile strength and electrical conductivity are 820 MPa/55.4%IACS and 713 MPa/61.3%IACS.
