Notes:
With different heat treatment, the microstructure and mechanical properties of ZK60magnesium alloy were investigated. It can be concluded that heat treatment has great effect onmechanical properties of ZK60. With artificial aging after extruding, the precipitation of the secondphase from the supersaturated solid solution significantly improved mechanical properties. It cangreatly increase yield strength of ZK60 alloy, while the tensile strength has little change. For thecombination of solid solution strengthening and age hardening, two opposite factors must beconsidered. On one hand, the solid solution strengthening and the later precipitation strengthening isgood for alloy’s strength; on the other hand, the properties decrease as the grains grew under hightemperature for a long time during solution heating
