摘要

采用不同铸造冷却方式(石墨模、水冷铜模)制备Cu-10Fe合金,研究了冷却方式对Cu-10Fe合金铸态组织和性能的影响.结果表明,冷却方式对Cu-10Fe合金抗拉强度和电导率影响显著.采用石墨模时,Fe元素在基体中固溶度降低,促进Fe相析出,对提高合金的电导率有利.采用水冷铜模时,合金组织明显细化,Fe元素在基体中固溶度增加,合金的抗拉强度、硬度显著提高,而电导率小幅下降,其抗拉强度为 299.1 MPa,硬度为 103.6 HV,电导率 49.58%IACS,综合性能良好.

Abstract

Cu-10Fe alloy was prepared adopting different casting cooling methods,such as graphite mold and water-cooled copper mold to study the effect of cooling methods on the microstructure and properties of Cu-10Fe alloy.The results show that the cooling methods have a significant effect on the tensile strength and electrical conductivity of Cu-10Fe alloy.When a graphite mold is used,the solid solubility of Fe elements in copper matrix decreases,promoting the precipitation of the Fe phase,which is beneficial for improving the electrical conductivity of alloy.When a water-cooled copper mold is used,the microstructure of the alloy is obviously refined,and the solid solubility of Fe in copper matrix increases.The tensile strength and microhardness of the Cu-10Fe alloy are en-hanced significantly,while the electrical conductivity decreases slightly.The tensile strength,micro-hardness and electrical conductivity of the Cu-10Fe alloy are 299.1 MPa,103.6 HV and 49.58% IACS,respectively,demonstrating satisfactory overall performance.
