放射光X線を用いたアルミニウム単結晶の 変形・再結晶中のその場観察
概要
Deformation and recrystallization mechanisms are worthy of a note as the controls in properties of metallic materials. In this study, deformation and recrystallization of aluminum single crystal were in-situ observed using synchrotron X-rays, and the recrystallization behavior was obtained. The specimen was deformed with plastic strain of 8 %, and was heated at 753 K. after 6 minutes from heating, the diffraction from subgrains were appeared in the diffraction pattern of the initial crystal. The subgrains coexisted with the initial crystal only for 30 seconds, and then the diffraction spots of the initial crystal disappeared due to recrystallization. Finally, the diffraction spots of the subgrain remained.
