摘要

利用Gleeble-1500热模拟机对半固态ZCuSn10合金的压缩变形行为进行了研究。结果表明

当应变速率、应变量相同时

压缩变形温度越高

半固态ZCuSn10合金试样的压缩变形应力就越低。当变形温度、应变量相同时

在未达到峰值应力前

半固态ZCuSn10合金试样的压缩应力随着应变速率的增加而增加。当应变速率、变形温度和应变量相同时

半固态ZCuSn10合金试样的压缩应力明显低于常规铸态的ZCuSn10合金压缩试样的压缩应力。

Abstract

The compression deformation behavior of semi-solid ZCuSn10 copper alloy was tested on the Gleeble-1500 thermal simulator.The results show that at the same strain rates and strain

with increasing in deformation temperature

the compression stress of the samples is declined.At the fixed deformation temperature and strain

before reaching the peak stress

the compress stress of the samples is increased with the increase of the strain rate.In addition

at the same strain rate

deformation temperature and strain

the compression stress of the semi-solid sample is obviously lower than that of the conventional cast sample.
