Outline of Final Research Achievements |
In this study, "crystal orientation dependence" of various physical properties such as plastic deformation behavior, elastic modulus, and degradable behavior in bcc-structured Mg-Li alloys were quantitatively determined by using the single crystals. It was clarified that each characteristic shows orientation dependence despite having a highly symmetric bcc structure. In addition, it was first clarified that the addition of 5 at.% of Al in the Mg-Li single crystal combined with rapid quenching caused an extreme increase in yield stress up to about 470 MPa; this compares to about 50 MPa in a Mg-Li binary crystal. Furthermore, it was found that by preparing an α/β two-phase alloy, it is possible to increase the strength while ensuring a certain degree of ductility.
