Research and Development in GH3536 Superalloy Processed by Laser Additive Manufacturing

Abstract:

Laser additive manufacturing, as an advanced digital forming technology, is widely used in the research of superalloy preparation. GH3536, as a solid solution strengthened nickel-based superalloy, is suitable for the preparation of components for combustion chambers of aero-engines due to its excellent mechanical properties. The control of metallurgical defects, microstructure modulation and mechanical property strengthening mechanism of laser additive manufacturing of GH3536 alloy were reviewed. The current research status and progress of laser additive manufacturing for GH3536 alloy were analyzed, and the research on the influence mechanism of its tensile and creep properties and other research was expected. It is hoped to provide reference for the research and development of laser additive manufacturing for GH3536 alloy.
