在液氮温度下，通过动态塑性变形制备了由纳米孪晶和纳米晶粒组成的块体纳米结构CuCrZr合金。通过一步变形处理的纳米结构CuCrZr合金的抗拉强度为700 MPa，电导率为78.5%国际退火铜标准。讨论了在不牺牲其高导电性的情况下提高强度的原因。(C)2014 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
A bulk nanostructured CuCrZr alloy consisting of nanotwins and nanograins was prepared by dynamic plastic deformation at liquid nitrogen temperature. A tensile strength of 700 MPa and an electrical conductivity of 78.5% International Annealed Copper Standard are obtained in the nanostructured CuCrZr alloys processed by means of this one-step deformation without aging treatment. The reason for the increased strength without the sacrifice of its high electrical conductivity was discussed. (C) 2014 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
