| Abstract: | The effects of different deforming temperature on the superplasticity of 2A12 aluminium alloywere experimented and discussed. The regulations of eleongation with different deforming temperature wereconcluded. The results show that 2A12 aluminium alloy obtained the best superplasticity at 470. The mechanisms were analyzed by observing microstructure of fractographs. |
