| 摘 要： | ZE10 magnesium alloy sheets were prepared through ingot casting and the hot-rolling process. The mechanical properties, conical cup value （CCV）, bore expanding performance, and limit drawing ratio （LDR） were investigated to examine the stamping formability of ZE10 alloy sheets, at temperatures ranging from 20 to 300℃. The results showed that the tensile strength decreased, whereas, plasticity, drawing-bulging performance, bore expanding properties, and deep drawing performance increased markedly at elevated temperatures. The CCV specimens could be drawn into the conical die＇ s underside cylindrical hole from the conical cliff, without cracking, and could have the minimum CCV at 200 and 250 ℃ In the bore-expanding test, the bore （φ10 mm） could be expanded to the dimension of the punch （φ25 mm） and the maximum bore-expanding ratio could be achieved at above 150℃. The limiting drawing ratio （LDR） of 2.85 is acquired during the deep drawing test at 230 v with the punch temperature of 20 - 50℃, the punch velocity of 50 mm · min^-1, and the mixture of graphite and cylinder grease as lubricant.
