| Abstract: | The influence of chemical composition, cooling rate of castings and heat treatment on the damping capacity of Mn-Cu alloy has been studied. The influence of Al on the SDC(specific damping capacity) depends on the heat treatment process. Silicon is harmful to the SDC and Rare Earth element can increase the SDC. According to the chemical composition and thickness of casting, proper heat treatment process has been suggested. |
| Keywords: | foundry heat treatment cooling rate Mn-Cu alloy damping capacity |
