Abstract: The effects of La on microstructures and mechanical properties of Zn-22%Al vibration alloy have been studied by measuring the curves of tensile strength versus natural ageing and artificial ageing time and by means of OM, TEM and SEM. The results show that La can refine the microstructure of Zn-22%Al alloy, slow down the grain growth and reduce the equiaxial degree during ageing, that the strength of Zn-22%Al (La)alloys and Zn-22%Al alloy remains constant after ageing below the warm rolling temperature, and that La can improve the strength and the stability of mechanical properties of Zn-22%Al alloy.
