| Research Abstract |
In order to develop novel lightweight high strength and highly heat-resistant magnesium alloys, we have performed fundamental and advanced research for long-period stacking ordered (LPSO) structure phase-containing Mg alloys. The LPSO phase-containing Mg alloy exhibits excellent mechanical properties such as high strength and reasonable ductility because LPSO phase suppresses a twin deformation. Furthermore, kink deformation occurs in the LPSO phase during plastic deformation. In this study, we have clarified the alloy strengthening by introduction of kink deformation band, and exhibited the criteria of alloy elements for formation of LPSO phase.
