Influence of Hot Isostatic Pressing, with or without Subsequent Heat Treatment, on the Structure of 3D-Printed Heat-Resistant Nickel Alloy

Key Points

• The aim is to understand how hot isostatic pressing and heat treatment affect the structure of a 3D-printed nickel alloy.
• Analyzed the structure of nickel alloy workpieces produced by plasma powder surfacing under varying conditions
• Conducted metallographic examinations to observe structural changes
• Structural changes were observed in the nickel alloy after hot isostatic pressing
• Heat treatment further influenced the macroscopic and microscopic structure of the alloy
