Effects of Aging Treatment on the Damping Capacities of ZA84-xSb Magnesium Alloys

Abstract

The effects of aging treatment on the damping capacities of ZA84-xSb alloys were studied. The results show that in the aging treatment process, because of following mainly reasons: (1) the dissolution of the ternary phases, (2) the increase of grain interfaces, (3) the increases of dislocation density, and (4) the micro deformations of matrix interfaces and the second phases, the damping capacity of ZA84-xSb magnesium alloys did not be reduced. On the contrary, whether at the low temperatures or high temperatures, its damping capacity is higher than as-cast alloy, which is of great significance for the application of ZA84-xSb magnesium alloys.
