Abstract：

ZK60 magnesium alloy electrical equipment shell specimens were prepared by isothermal forging method, and the microstructure, mechanical properties and corrosion resistance of specimiens were tested and analyzed,which was compared with commercial conventional forged ZK60 magnesium alloy. The results show that the isothermally forged high-performance ZK60 magnesium alloy electronic equipment shell has an internal microstructure with fine equiaxed crystal morphology. The average grain size of the alloy is 6.7 μm,which is 11.8 μm smaller than that of commercial conventional forged alloy, and the yield strength and tensile strength of the alloy are 396 and 322 MPa, respectively,which are 121 and 108 MPa higher than those of to commercial conventional forged alloy, respectively. The elongation after fracture of the alloy is 21.1%,showing no significant difference from commercial conventional forged alloy. After corrosion for 100 h, the weight loss per unit area is 20.9 mg·mm-2 less than that of commercial conventional forged alloy. The isothermally forged ZK60 magnesium alloy of electronic equipment shell has good mechanical properties and corrosion resistance.
