摘要
在新型镍基单晶高温合金中单一添加合金元素Ti、Nb、La,以及复合添加合金元素Ti/Nb/La,并进行了显微组织、力学性能和持久性能的测试与分析。结果表明,与单一添加合金元素Nb相比,复合添加合金元素Ti/Nb/La合金的持久性能提高176%。
In new single adding alloy elements in nickel base single crystal superalloy Ti, Nb, La, and composite Ti/ Nb/La adding alloy element, and has carried on the microstructure, mechanical properties and lasting performance test and analysis. Results show that compared with single adding alloying elements Nb, composite add alloy element Ti/Nb/La is durable performance increased by 176%.
