| Outline of Final Research Achievements |
In this study, the relationship between the dislocation structures in the metastable parent phase and subsequent deformation-induced martensitic transformation (DIMT) was examined in several structural alloys, such as biomedical Co-Cr-Mo alloys, titanium alloys, and high entropy alloys. It was demonstrated that introducing parent phase’s dislocations accelerated or retarded the γ (fcc) → ε (hcp) DIMT, depending on the alloy composition. The obtained results are helpful for designing novel structual alloys with an enhanced combination of strength and ductility.
