PREDICTED CONSTITUTIVE MODELING OF HOT DEFORMATION FOR AZ31 MAGNESIUM ALLOY
ACTA METALLURGICA SINICA
The uniaxial compression tests of AZ31 magnesium alloy at different strain rates of 0.01-10 s −1 and different deformation temperatures of 523-723 K were performed by using Gleeble-1500 simulator with a maximum strain of 0.916. The influences of deformation temperature and strain rate on the flow stress were investigated. The fine microstructure is attributed to dynamic recrystallization during compression process at 523 K. The stretched grains of dynamic recrystallization and growth up alongdoi:10.3724/sp.j.1037.2011.00641 fatcat:xfxj77vwanb2ljmss5n3fsbaaq
