研究了 AZ31 镁合金板材在 200 至 300°C 温度范围内的成形性能。通过执行基于 Nakazima 的测试获得了成形极限图。已经使用具有多种长宽比的板坯研究了不同的应变条件。成形极限曲线与变形过程中发生的微观结构演变有关。成形极限图显示成形性随温度的升高而显着增加，这可能与 300°C 时发生完全动态再结晶有关。
The formability of AZ31 magnesium alloy sheets has been investigated in the temperature range varying from 200 to 300°C. Forming limit diagrams have been obtained by performing Nakazima-based tests. The different straining conditions have been investigated using sheet blanks with several length to width ratios. The forming limit curves have been related to the microstructural evolution occurring during deformation. The forming limit diagrams have shown a remarkable increase in formability with temperature that could be related to the occurrence of full dynamic recrystallization at 300°C.
