- 摘要:
- Inconel 625因其优异的综合性能广泛应用于各种工业领域。随着各行业的发展,对Inconel 625合金的性能要求越来越高,因此进一步改善Inconel 625合金的组织及性能非常必要。本文总结了近7年国内外学者对Inconel 625合金成型制备、组织性能、熔盐腐蚀等方面的研究,其中成型方法从3D打印技术(即增材制造)、表面改性技术等方面综述;性能方面主要总结了化学成分和热处理工艺;熔盐腐蚀方面重点讨论了氟化物盐、硝酸盐、碳酸盐、硫酸盐等。最后,提出了Inconel 625合金未来的发展前景,为以后Inconel 625的研究提供了实际性的指导。
Inconel 625 is widely used in various industrial fields due to its excellent comprehensive performance. With the development of various industries, the performance requirements of Inconel 625 alloys are increasing. Therefore, it is very necessary to further improve the microstructure and properties of the Inconel 625 alloy. This paper summarizes the research of molding preparation, microstructure and properties, molten salt corrosion and other aspects of Inconel 625 alloy in the past seven years, among which the forming methods are reviewed from 3D printing technology (i.e., additive manufacturing) and surface modification technology. In terms of performance, the chemical composition and heat treatment process are mainly summarized. In molten salt corrosion, fluoride salt, nitrate, carbonate, sulfate and so on are discussed. Finally, the future development prospects of Inconel 625 alloy are also presented. This work provides practical guidance for future Inconel 625 research.
