摘要： 采用Gleeble-1500热模拟机对用近液相线铸造方法制得的半固态ZL201合金进行了不同温度和不同应变速率下的压缩变形,并对实验结果进行了回归处理,建立了半固态ZL201合金在不同变形温度、不同应变速率下的数学模型.研究结果表明:当应变速率相同时,压缩应力随变形温度的增加而减小;当应变温度相同时,压缩应力随着应变速率的增加有先增大后减小的趋势.本实验可为半固态合金触变成形的数值模拟和优化半固态金属加工工艺参数提供基础数据.

Abstract: The compression deformation of the semi-solid ZL201 aluminum alloy, prepared by the near-liquids continuous casting, was conducted on the Gleeble-1500 thermal simulator at different temperatures and strain rates. Then, a mathematic model was developed correspondingly via the regression analysis of simulation results. It was revealed that the higher the deformation temperature, the lower the compression stress if the strain rate is constant, and the compression on stress increases first then decreases with increasing strain rate if the deformation temperature is constant. The results can also provide the basic data for the numerical simulation of semi-solid alloy thixoforming and the optimization of process parameters for semi-solid metals.
