[191] Strain-rate dependence of serration behavior in high-Mn steels having different grain sizes

*Sukyoung Hwang1, Ryo Asada1, Myeong-heom Park1, Nobuhiro Tsuji1,2 (1. Department of Materials Science and Engineering, Kyoto University, 2. Elements Strategy Initiative for Structural Materials (ESISM), Kyoto University)

Keywords:高Mn鋼、セレーション挙動、Portevin–Le Chatelier (PLC) バンド、結晶粒の微細化、ひずみ速度感受性

本研究では、異なる平均粒径を持つ高Mn鋼を作製し、変形応力のひずみ速度依存性を系統的に調査することで、セレーション挙動の変化とそれに伴う加工硬化率の変化の要因を明らかにした。
