Outline of Final Research Achievements |
We have clarified the martensitic transformation, crystal structure, internal defect and martensite variant of the equiatomic binary alloys combined with IV and X groups. A long period stacking order with 6O structure of the martensitic phase in a Hf-Co-Pd alloy was identified by conventional transmission electron microscopy and high-angle annular dark-field scanning transmission electron microscopy. The ductile precipitate formed by replacement of third element, such as Pd and Pt, remarkably increases the strength and elongation in B2-type Fe-Co alloy.
