Effect of Deformation Temperature on Microstructure and Properties of ZK60 Sheet Bending and Straightening

The tensile twins were successfully preset in the ZK60 magnesium alloy sheet through the bending and straightening process, and the effect of different deformation temperature on the structure and properties of the sheet was studied. The results show that the tensile strength of ZK60 sheet can be improved and the yield strength can be reduced through the bending and straightening process. As the deformation temperature increases, the yield strength of the sheet increases significantly, and the tensile strength and elongation after fracture slightly increase.
