High temperature nickel base alloy is one of the most important high-temperature alloy materials in the aerospace field

which has excellent fatigue resistance and creep characteristics under high temperature and high-pressure conditions. In this paper

we summarized the research progress on rapid manufacturing of high temperature nickel base alloy parts through laser powder bed fusion at home and abroad. First the authors systematically introduced several mature nickel base superalloys and that are still during development of nickel base alloy

then summarizes microstructure and defects characteristics of the SLMed nickel base alloy

and the corresponding changes of microstructure and mechanical properties after heat treatment. At last

several existing hot issues are also listed for SLM fabrication of nickel base alloy.
