摘要
本文对供应状态的LY12R和LY12CZ合金棒材的超塑性等温压缩试验结果进行讨论,分析了压缩变形过程,确认未经任何超塑预处理的供应状态LY12合金具有轻微超塑性能,确定了两种状态的LY12合金的最佳变形工艺参数,研究了试样尺寸对压缩变形过程的影响。本试验结果为压缩类成形零件提供了较佳的工艺参数。
The author discusses in this paper the results of superplastic isothermal co- mpression experiment which carried on LY12R and LY12CZ alloy bars in supply condition. With respect to LY12 alloy without any pretreatment and in supply condition, a slight superplasticity is affirmed by the analysis of compression de- formation process. The optimum technological parameters of deformation for LY12 alloy in two conditions are determined. The effect of the dimension of specimen on the process of compression deformation is studied. These results provide fai- rly good technological parameters for those parts formed by compression:
