Vibration damping which is an effective application in vibration and noise control is a field of comprehensive technology on the basis of dynamics and material science. In order to improve the capability of vibration damping of structure materials, innovation must be carried out from the aspect of basic theory and preparation techniques. The techniques of founding, modification, solution heat treatment and ageing are systematically introduced in this paper. Microstructures of Zn-27A1 alloy are analyzed. The...
