| Abstract: | The effect of heat treatment on hardness and impact toughness of polynary Copper alloy has been studied by means of metallographic, XRD, SEM/EDS, TEM and mechanical property test. The results show that the heat treatment can change the hardness of polynary Copper alloy, and has the weak influence to its impact toughness. Higher hardness of polynary Copper alloy could be obtained by tempering at 500 ℃ for 2 h. |

| Keywords: | Copper alloy heat treatment hardness and impact toughness. |
