| Outline of Final Research Achievements |
In this study, microstructure development process and influences of microstructure on mechanical properties in dual phase magnesium alloys were investigated. As model materials for dual phase magnesium alloys, long-period stacking ordered (LPSO) type Mg-Zn-Y alloys with different volume fraction of LPSO phase are used. Several important insights have been gained including (i) effect of microstructure on mechanical properties in as-cast alloys, (ii) distinctive microstructure development during cyclic loading in as-cast alloys, (iii) nonlinear unloading behavior in as-cast and extruded alloys, (iv) development of analysis method for lattice strain evaluation, (v) parameter identification for extruded alloys, and (vi) application of developed analysis method to dual phase materials other than LPSO type Mg-Zn-Y alloys.
