Deformation and Workability Evaluation of GW103K Magnesium Alloy in Hot Compression
Gleeble 3500 thermo mechanical simulator was used to perform hot compression tests of GW103K (Mg-10Gd-3Y-0.6Zr) magnesium alloy at a temperature range of 573K-723K and strain rates of 0.001 1 s? -1 1 s?.The workability of the alloy can be evaluated by means of processing maps on the basis of dynamic materials model (DMM) and the superior processing condition is selected.Combining true compression stress-strain curves with the results of microstructure observation,it was found that the peak stress decreased observably as the decrease of strain rate and the increase of deformation temperature.Constitutive equation is built to reveal the accurate relationship among flow stress,temperature and strain rate.
