摘要： 采用Gleeble1500热模拟机,研究了半固态ZL201铝合金的压缩变形过程以及不同应变速率、变形量及变形温度对触变强度的影响.研究结果表明:当应变速率相同时,变形温度越高,ZL201合金半固态试样的触变强度越低.当变形温度相同时,在较低应变速率下(.ε<5s-1),随着应变速率的增大,ZL201合金半固态试样的触变强度增大;在较高应变速率下(.ε>5s-1),随着应变速率的增大,触变强度又有减小的趋势.结果可为半固态成形工艺参数制定提供基础数据.

Abstract: The compression deformation process of the semi-solid alloy ZL201 and the influence of its strain rate and deformation extent/temperature on the thixoforming stress were investigated on the Gleeble-1500 thermo-simulator. It was revealed that the higher the deformation temperature, the lower the thixoforming stress of specimens at the same strain rate. On the other hand, if the deformation temperature remains unchanged and the strain rate Ε˙<5 s-1, the higher the strain rates, the higher the thixoforming stress. And if Ε˙>5 s-1, the thixoforming stress tends to decrease with increasing strain rate. The results can provide the basic data for the optimization of process parameters of semi-solid metals.
