摘要
高强高韧钽基合金是航空发动机用新型候选超高温结构材料之一,综述了为改善钽基合金综合力学性能而采用的固溶强化、析出相强化、细晶强韧化以及形变强化等方法,指出了存在的问题及发展趋势。
The tantalum based alloys with high strength and toughness are one kind of new candidate ultra-high- temperature structural materials for areo-engine applications. Some methods for improving the comprehensive mechanical properties were reviewed, such as solid solution hardening, precipitated-phase strengthening, fine-grained strengthening and toughening, as well as deformation strengthening Furthermore, some existing problems and development prospects were suggested
