| Outline of Final Research Achievements |
To understand the details of the formation and strengthening mechanisms of the synchronized LPSO structures, it is required to elucidate their atomic structures and establish the science of their electronic and structural properties. In this study, we successfully characterized the main factors that dominate the solute-atom and/or solute-cluster ordering in the Mg-based LPSO structures at the electronic and atomic levels through first-principles-based computational science. This supported the validity of models of atomic structures obtained from the experiments, and also promoted the collaborations between experimental and computational researches. In addition, we clarified the activation mechanisms of basal slip systems in the LPSO phases and those of some non-basal slip systems in the Mg matrix on the basis of first-principles calculations.
