Characterization of semisolid deformation behavior of a high Zr-containing WE magnesium alloy
文献摘要：
The effects of temperature and strain rate on the semisolid deformation behavior of a high Zr WE54 mag-nesium alloys were studied at temperatures of 570,595 and 620℃.A flow stress peak was appeared during defor-mation of the feedstock experimental material at defor-mation conditions of 570℃,0.010 and 0.100 s-1,and 595℃,0.100 s-1.The latter results were connected to the occurrence of dynamic recrystallization in solid globules.Also,these conditions were gauged to be able to activate"lubricated flow"mechanism.At 570℃and strain rate of 0.001 s-1 as well as 595℃and rates of 0.010 and 0.001 s-1,the flow stress increases and reaches a plateau,where dynamic recovery is considered as the dominant mechanism.However,at 620℃under all the strain rates,the flow stress drops for a limited strain range and then increases again.The results show that as the liquid removes from the boundaries between the solid parts,the densifi-cation of the globules occurs at higher strains,causing an increase in the flow stress.Comparative analysis points out that the feedstock material exhibits a lower flow stress than as-cast alloy associating with a modified morphology of Zr particles after deformation.
