A Study of Dynamic Recrystallization and Superplasticity of Received Lyizcz Al-Alloy
Yao Zubin Zhang Jinyun (Hua Qiao University)
This paper deals with the maehanical behavior and microstructure of received LY12Cz Al-alloy under superplastic deformation without any pretreament. The oecurrence of dynamic rccrystallization of LY12Cz Al-alloy during isothermal compression was confirmed. The dynamic recrystallizatin could cause superplasticity. when a new lubricant of D was used, a better superplas-ticity could be obtained during fast deformation. It is worth while wide yusing this technique in practical deformation.
