摘要
用Gleeble1500高温拉伸试验机研究了添加元素Ag，Sb，Sn对Cu－P合金高温性能的影响．研究结果表明，Ag能显著提高Cu－P合金在室温下的综合性能，Sb和Sn能显著提高Cu－P合金在150～280℃时的强度，其中的Sn强化效果最好．但当合Sn＞5％时，会使Cu—6．5P合金的室温脆性增大．
The effect of the addition of Ag,Sb,and Sn on the high -temperature properties of Cu -P alloy is investigated by using Gleeble 1500 bigb-temperature tensile testing machine. The results show that Ag can improve the room- temperature mechanical properties of Cu -P alloy markedly and Sb and Sn can improve the strength of tbe alloy at 150~280℃ markedly. Sn is the most effective strengthening element. But the brittlenese of Cu- 6. 5P alloy at room-temperature increases wben Sn addition is above 5%.
