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%.
