| Abstract: | Additive Manufacturing (AM) is an advanced digitalized technology that has been extensively applied in the fabrication of high temperature alloys. This paper reviews the microstructure of high temperature alloys prepared by AM, summarizes the type and features of pores, and categorizes the development of models interpreting the formation of cracks. The application of computational science in the research of preparation of high temperature alloys was also reviewed. Finally, the prospect of AM in the research and development of high temperature alloys was discussed. |
