利用粉末冶金法制得了板型规整的纯钼烧结坯,在Gleeble-1500型热模拟实验机上对纯钼板坯进行热压缩变形实验,变形温度为1100°C~1300 °C、变形速率为0.01~10 s-1、真应变为0.3~0.6。分析不同变形条件下纯钼热压缩真应力-应变曲线,利用Origin软件绘制纯钼高温塑性变形真应力-应变曲线图。
A pure molybdenum sintered compact with a regular plate shape was prepared by powder metallurgy. The pure molybdenum slab was subjected to a thermal compression deformation experiment on the Gleeble-1500 thermal simulation test machine. The deformation temperature was 1100°C~1300°C, and the deformation rate was 0.01~ 10 s-1, the true strain is 0.3 to 0.6. Analyze the true stress-strain curve of pure molybdenum thermal compression under different deformation conditions, and use Origin software to draw the true stress-strain curve of pure molybdenum high temperature plastic deformation.
