摘要

采用粒径为10、25、40μm的金属Cu粉与平均粒度为3μm的W粉

通过伪半固态触变挤压铸造制备了W-40Cu合金筒形件。结果表明

在加热温度为1350℃、挤压力为500MPa的条件下

减小Cu粉粒径有利于触变挤压铸造成形件力学性能的提高;Cu粉粒径越细

成形件导电性能越好。

Abstract

Thixo-die-forging process in pseudo-semi-solid state was used to prepare W-40Cu cup shell with copper particle size in 10μm

25μm

40μm and tungsten particle size in 3μm.The results show that with the heating temperature of 1 350℃and applied pressure of 500MPa

the decrease of copper particle size is favorable for the improvement of mechanical properties of thixoforged parts.With the copper particle size decrease

conductive properties of thixoforged parts are increased.
