Fig. 9. Processing maps for Mg-Gd-Y-Nb-Zr alloy generated at strains of: (a) 0.1; (b) 0.2; (c) 0.3; (d) 0.4; (e) 0.5; (f) 0.6. The numbers represent percent efficiency of power dissipation and shaded areas correspond to instability regions. The processing maps are divided into three domains by red lines: domain I, domain II and domain III, meanwhile, the instability regions are defined as region 1 and region 2.
