| 摘 要： | Mechanical properties and tribological behavior of a novel cast heat-resisting copper based alloy are investigated. The corresponding properties of a commercial aluminum bronze C95500 (ASTM B30) are compared with the alloy. The results show that the alloy possesses better mechanical properties and tribological behaviors than that of C95500 at elevated temperature. The tensile strength, elongation and hardness at 500℃ are 470MPa, 2.5% and HB220, respectively. The wear rate of the developed alloy at ambient and elevated temperature is about one-sixth and one-fortieth of that of C95500, respectively. The alloy is very suitable for ma-nufacturing heat-resisting and wear-resisting parts. Major strengthening mechanisms for the alloy are solution strengthening and the second phase strengthening.

| Abstract: | Mechanical properties and tribological behavior of a novel cast heat-resisting copper based alloy are investigated. The corresponding
properties of a commercial aluminum bronze C95500 (ASTM B30) are compared with the alloy. The results show that the alloy
possesses better mechanical properties and tribological behaviors than that of C95500 at elevated temperature. The tensile
strength, elongation and hardness at 500°C are 470MPa, 2.5% and HB220, respectively. The wear rate of the developed alloy
at ambient and elevated temperature is about one-sixth and one-fortieth of that of C95500, respectively. The alloy is very
suitable for ma-nufacturing heat-resisting and wear-resisting parts. Major strengthening mechanisms for the alloy are solution
strengthening and the second phase strengthening.
