| Popis: | Due to the accumulation of slip and twinning, the deformed structure of the wrought magnesium alloy is unevenly distributed, resulting in stress concentration, leading to its poor formability. Microstructure evolution in dense areas and sparse areas of deformed structure at different annealing temperatures are explored in this study, and the competitive relationship between the nucleation and growth of recrystallization at different temperatures and its influence on the uniformity of the structure are analyzed. Annealing temperature can improve the uniformity of the deformed structure of wrought magnesium alloys by affecting the sequence of recrystallization in dense areas of the deformed structure and grain growth in sparse areas of the deformed structure. |
