Abstract:

Laser additive manufacturing, as an advanced digital forming technology, is widely used in the research of high temperature alloy preparation.GH3536, as a solid solution strengthened nickel-based high temperature alloy, 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 are reviewed. The current research status and progress of laser additive manufacturing of GH3536 alloy are analyzed, and the research on the influence mechanism of its tensile and creep properties and other research is expected. It is hoped to provide reference for the research and development of laser additive manufacturing of GH3536 alloy.
