Abstract:

e The effects of static annealing on recovery, recrystallization and grain growth in a magnesium AZ31B-H24 alloy sheet are investigated at 50°C to 450°C. Full recrystallization is observed after annealing at 250°C or higher temperatures. Recrystallized grain size increases with temperature through normal grain growth. Room-temperature hardness drops abruptly following recrystallization and then decreases with increasing grain size. Predictive relationships are proposed for recrystallized grain size as a function of temperature and time and for hardness as a function of recrystallized grain size.The effects of recrystallization and grain growth on plastic flow and anisotropy will also be discussed.
