Description:

(abstract)

In powder bed fusion (PBF) additive manufacturing (AM), local heating by laser (LB) or electron beam (EB) irradiation produces an extreme thermal gradient exceeding 10^7 K/m, referred to as a super-thermal field. This leads to ultra-rapid cooling above 10^6 K/s and crystal growth rates approaching 10 m/s -conditions that are difficult to realize in conventional casting or welding. Under such circumstances, unique crystal growth phenomena such as absolute stability emerge, opening new possibilities for innovative materials creation. This presentation summarizes the achievements of the JSPS Transformative Research Area (A) project "Creation of Materials by Super-Thermal Field" initiated in FY2021, and discusses the future outlook of materials science enabled by AM.
