High strength Zn-35Al-3.5Mn-2.2Cu-0.1Mg alloy was prepared by sprayed-forming method.Microstructure and mechanical properties of the alloy with solid solution at different temperature and holding times were investigated by XRD（X-ray diffraction） and SEM（scanning electron microscope） as well as tensile testing.The results indicate that microstructure of the alloy treated by two-stage solid solution is more desirable than that treated by single solid solution

where recrystallization grain size exhibits very fine with more dissolved precipitates.Tensile strength and yield strength

elongation of the alloy with two-stage solid solution at 360℃ for three hours and 390℃ for one hours reach up to 536MPa and 471 MPa

9.2%

respectively.
