Harjo, S. ; Aizawa, Kazuya ; Gong, W. ; Kawasaki, Takuro ; Yamasaki, Michiaki*

In this study, in situ neutron diffraction during deformation was performed using three kinds of samples of Mg $_{97}$ Zn $_{1}$ Y $_{2}$ alloy: an as-casted sample (As-Cast), hot extruded samples with the extrusion ratio (R) values of 5.0 (R=5.0) and 12.5 (R=12.5). Crystallographic evolutions of Mg and LPSO phases by hot-extrusion and deformation behavior of the individual phases were investigated, and the unique deformation mechanism by hot-extrusion in this alloy will be discussed based on the obtained results.
