摘　　要：对ZE10镁合金板材在20～250℃进行了非等温拉深实验研究。结果表明:随着变形温度升高,ZE10镁合金板材的拉深性能明显改善;230℃拉深时,用石墨+气缸油混合物作润滑剂、在冲头温度为20～50℃、拉深速度为50mm/min的条件下,可顺利拉深最大直径为142.5mm的板料,极限拉深比为2.85。Nonisothermal deep drawing tests for the ZE10 magnesium alloy sheet were conducted in a temperature between 20℃ and 250℃. It is indicated that the deep drawing performance has been significantly improved at elevated temperature. In the condition that the mixture of graphite and cylinder grease is applied as a lubricant, the punch temperature is between 20℃ and 50℃,and the deep drawing velocity is 50 mm/min, the sheet tan with a diameter of 142.5 mm can bc deep drawn into the blank successfully at 230℃. The acquired limiting drawing ratio is 2.85.
