[J26] Effect of Stacking Fault Energy on Microstructural Evolutions and Mechanical Properties of FCC Metals Processed by Severe Plastic Deformation

*ASANO Mayu1, MIYAMOTO Hiroyuki2, YUASA Motohiro2 (1. 同大理工(院生)、2. 同大理工)

Keywords:強ひずみ加工、ECAP、超微細粒組織、積層欠陥エネルギー、FCC金属

FCC金属に対し強ひずみ加工を行い、合金元素の持つ積層欠陥エネルギーを低下させる効果と転位への固着の効果を分離し、超微細結晶粒変形機構と機械的性質に及ぼす影響を明らかにする。
