## Description

- description: 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.
