[257] Fabrication of High-Strength SUS316L Steel by Laser-Powder Bed Fusion (L-PBF)

*Akiyoshi UCHISHIBA1, Ryosuke OZASA2,3, Kazuhisa SATO4, Takahiko KIKUCHI5, Ryo OTSUKA5, Shingo KATAYAMA5, Masaaki SUGIYAMA6, Takayoshi NAKANO2,3 (1. Osaka Univ. Eng., 2. Osaka Univ. Grad. Eng., 3. Osaka Univ. AM Center, 4. Osaka Univ. Research Center for UHVEM, 5. Nippon Denko Co., Ltd., 6. JSHT)

Keywords:stainless steel、additive manufacturing、equiaxed solidification

SUS316Lステンレス鋼に対して、微細粒子添加とL-PBFによる超急冷を重畳することで、微細粒子の均一分散に基づく結晶粒微細化を実現し、本合金の高強度化を達成した。
