摘要
通过等温压缩试验和金相分析研究了变形温度、变形程度、应变速率对Co40NiCrMo合金微观组织的影响,研究结果表明:再结晶晶粒尺寸随着变形温度的增加而增大;随着应变速率的增大呈先减小后略有增大的趋势,再结晶体积分数随着变形程度的增加而增大,晶粒尺寸随着变形程度的增加而减小。
The influence of deformation temperature and strain rate on microstructure of Co4NiCrMo Alloy has been analyzed by isothermal compression test and metallurgical analysis.The results show that the grain size increases with the increase of deformation temperature and the grain size decreases with the increase from 0.001s^-1 to 1s^-1 of strain rate,but increases slightly with the increase from 1s^-1 to 10s^-1 of strain rate.The recrystallization volume fraction increases with the increases of strain and the grain size decreases with the increase of strain.
