[94] Effect of Supersaturated Vacancies Induced by Laser-Beam Irradiation for Powder Bed Fusion on Spinodal Decomposition in Fe-Cr-Co Alloys

*Yuheng LIU1, Takato Saito1, Masayuki Okugawa1,2, Kazuhisa Sato3, Yuichiro Koizumi1,2, Takayoshi Nakano1,2 (1. Osaka Univ., 2. Osaka Univ. AM center, 3. Osaka Univ. UHVEM)

Keywords:Fe-Cr-Co、スピノーダル、粉末床溶融結合、過飽和空孔、レーザー照射

Fe-Cr-Co合金にPBF用レーザーを照射した後, 多段熱処理を行って,TEMによる過剰空孔が急速溶融・冷却領域のスピノーダル分解挙動に与える影響を調査した.
