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。The compression deformation behavior of semi-solid ZCuSnl0 copper alloy was tested on the Gleeble-1500 thermal simulator. The results show that at the same strain rates and strain, with increas- ing in deformation temperature, the compression stress of the samples is declined. At the fixed deforma- tion temperature and strain , before reaching the peak stress, the compress stress of the samples is in- creased 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 conven- tional cast sample.
