A Review of Research of Microstructure and Defects in Ni-Based Superalloys Fabricated by Selective Laser Melting
Selective laser melting(SLM)is an advanced digitalized technology that has been extensively applied in the fabrication of superalloys.This paper reviewed the microstructure of superalloys prepared by SLM,summarized the type and features of pores,and categorized the development of models interpreting the formation of cracks.The application of computational science in the research of preparation of superalloys was also reviewed.Finally,the prospect of SLM in superalloys was discussed.
