Superplasticity and diffusion bonding of magnesium alloy ZK60① (...

Superplasticity of as-rolled ZK60 magnesium alloy sheets, with the average grain size of 8.2μm, was investigated at a strain rate of 5.56×10-4 -5.56×10-2s-1 at 573-673K. The microstructure evolution during the superplastic deformation shows that the alloy
