喷射成形高温合全具有成分均匀、无宏观偏析、氧含量低、晶粒细小等特征,同时具有较好的综合性能,是喷射成形研究的重要方向和活跃的前沿。简要介绍了喷射成形的基本原理,并对国内外喷射成形高温合金的研究进展情况进行综合评述。
Spray forming high-temperature all-in-one has the features of uniform composition, no macroscopic segregation, low oxygen content, small grain size and the like, and has good comprehensive properties at the same time. It is an important direction and an active forefront of spray forming research. The basic principle of spray forming is briefly introduced. The progress of research on spray forming superalloy at home and abroad is reviewed.
