Title: Effect of Deformation Degree on Dynamic Recrystallization of As-cast AZ31 Alloy
Abstract:The dynamic recrystallization law of as-cast AZ31 alloy was investigated during hot compression deformation at 250~425 ℃ and various deformation degree(10%~40%) under the strain rates of 0.01 s-1.The ...The dynamic recrystallization law of as-cast AZ31 alloy was investigated during hot compression deformation at 250~425 ℃ and various deformation degree(10%~40%) under the strain rates of 0.01 s-1.The relationship between flow stress and deformation degree was analyzed.The results show that the alloy breaks when the deformation degree approaches to 40%.With the increase of deformation degree,the flow stress of AZ31 alloy increases to the peak first and then decreases at constant deformation temperature and strain rate during hot compression deformation,which exhibits the characters of dynamic recrystallization.And the more the deformation degree increases,the more the grains of dynamic recrystallization.Read More
