Abstract  

The static recrystallization of hot-deformed magnesium alloy AZ31 during isothermal annealing were investigated at temperature 503 K by optical and SEM/EBSD metallographic observation. The grain size (D) change during isothermal annealing is categorized into three regions, i.e. an incubation period for grain growth, rapid grain coarsening, and normal grain growth. The number of fine grains per unit area, however, is reduced remarkably even in incubation period. This leads to grain coarsening taking place continuously in the whole period of annealing. In contrast, the deformation texture scarcely changes even after full annealing at high temperatures. It is concluded that the annealing processes operating in hot-deformed magnesium alloy can be mainly controlled by grain coarsening accompanied with no texture change, that is, continuous static recrystallization.

Key words:  metallic materials        hot deformed magnesium alloy       annealing       microtexture       continuous recrystallization
