文摘Using natural aging and artificial aging treatment, the effects of cerium on microstructures and mechanical properties of Zn 22%Al vibration damping alloy were studied by optical microscope, transmission electron microscope and scanning electron microscope.

The strength of Zn 22%Al (0 07%~0 20%)Ce alloy and Zn 22%Al alloy remains constant after aging below the hot rolling temperature of 80 ℃, and cerium can improve the strength and the stability of mechanical properties of Zn 22%Al alloy.
