Effect of heat treatment on the microstructural evolution and mechanical properties of GH4099 fabricated by lase powder bed fusion

In this study, the effect of solution and aging heat treatments on the microstructure and mechanical properties of GH4099 superalloy fabricated lase powder bed fusion (L-PBF) was investigated.The microstructure of as-manufactured L-PBF-built GH4099 alloy has elongation grain with an average grain si...
