Formability of AZ31 magneisum alloy sheets for complex shape components was investigated by deep drawing experiment.Effects of deep drawing processing parameters on quality of deep drawing magnesium alloy piston shell were analyzed
such as formation temperature
drawing velocity
billet heating time and lubrication condition.The results indicate that adopting forming temperature of 290~350 ℃
drawing velocity of 0.1~0.2mm/s and heating time of 5~10 min as well as MoS2+ oil as lubricant
qualified complex magnesium alloy piston shell is successfully drawn.
