Outline of Final Research Achievements

A long-period stacking ordered (LPSO) structure often formed in Mg-based alloys is characterized by the periodical arrangement of stacking fault introduced on the hcp matrix and additive atoms segregate in the stacking fault layers. Therefore the LPSO structure has synchronized structural and compositional modulations. Because the LPSO structure might possibly play a key role in fabricating new magnetic materials or superconducting magnets, a precise understanding of LPSO structure formation is so important. Therefore in the present study the formation mechanism of LPSO structure was investigated from a viewpoint of structural and compositional modulation. Based on the criteria, some candidate alloys were produced to check the physical properties.
