本文采用1KW横流CO_2激光器研究了在不同激光熔凝和后续热处理条件下GH37合金表层的显微组织特征,为激光快速熔凝技术在沉淀硬化型高温合金中的应用提供了一定的试验依据。
In this paper, the 1KW cross-flow CO_2 laser was used to study the microstructure of the GH37 alloy under different laser and subsequent heat treatments, which provided some experimental basis for the application of laser rapid fusion technology in precipitation hardening superalloy.
