组元体积占比对CuCrZr-Cu层状异构材料力学和电学性能的影响
Composition-Dependent Evolution of Mechanical and Electrical Properties in CuCrZr-Cu Laminated Heterogeneous Materials
摘要
Abstract
In order to achieve a good balance between strength and electrical conductivity of copper alloys,pure copper was used as the soft component,and CuCrZr alloy was used as the hard component.A series of CuCrZr-Cu laminated heterogeneous materials with vary-ing volume fractions of pure copper component were prepared using vacuum hot-pressing sintering combined with thermomechanical treatment.The influence and mechanism of the volume fraction of pure copper component on the mechanical and electrical properties of CuCrZr-Cu laminated heterogeneous materials were investigated.The results showed that as the volume fraction of pure copper com-ponent increased from 12%to 50%,and the yield strength of the material decreased from 603 MPa to 501 MPa.In addition,the electri-cal conductivity increased from 80.1%IACS to 87.6%IACS,and the uniform elongation increased from 5.4%to 11.9%.During the de-formation process,the mutual constraint between the components was enhanced with the increase in the volume fraction of pure copper component.This enhanced mutual constraint promoted the generation and accumulation of geometrically necessary dislocations(GNDs)within the grains,thereby increasing the extra strengthening effect.关键词
