摘　　要：对AZ31及ZE10镁合金板在20～300℃条件下进行了力学性能、弯曲及锥杯试验。研究结果表明:随着变形温度升高,镁合金板材强度下降而塑性、弯曲性能、“拉深+胀形”复合成形性能明显改善。ZE10镁合金板比AZ31镁合金板具有更好的弯曲及拉胀复合成形性能。200℃、250℃试验时,ZE10镁合金锥杯试样可顺利拉深进入锥杯底部圆孔而不出现裂纹。The mechanical properties, bending formality and conical cup value (CCV) of AZ31 and ZE10 magnesium alloys were investigated at the temperatures ranging from 20~300 ℃. The results show that the tensile strength can be decreased while the plasticity, bending formality and the drawing-bulging performance of the AZ31 alloy and ZE10 alloys can be obviously improved with the increasing in deformed temperature. ZE10 alloy sheets show a better bending formality and drawing-bulging performance compared with AZ31 alloy sheet. When tested at 200 ℃ and 250 ℃, the ZE10 magnesium alloy samples can be drawn into the round hole underside the conical cup with no advents of the fracture.
