[J23] Effect of Stacking Fault Energy and Solute Atom on Microstructural Evolutions and Mechanical Properties of Cu and Cu-Mn by Severe Plastic Deformation

*ASANO Mayu1, MIYAMOTO Hiroyuki2, YUASA Motohiro2 (1. Doshisha Univ.(Grad.), 2. Doshisha Univ.)

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

CuとCu-Mn合金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変化させる効果と転位への固着の効果を分離し、超微細結晶粒形成機構と機械的性質に及ぼす影響を明らかにする。
