Outline of Final Research Achievements |
Mechanical properties of Ti alloys are strongly influenced by the interstitial alloying elements such as oxygen and nitrogen, which are unavoidable impurities in Ti alloys. In this study, the effects of interstitial alloying elements such as oxygen and nitrogen, on microstructure, mechanical properties and transformation and deformation behavior of meta-stable Ti alloys were investigated. The mechanism and origin of anomalous properties such as isothermal martensitic transformation under a constant stress, invar-like behavior and large nonlinear elastic strain with near zero hysteresis observed in Ti alloys containing a larger amount of interstitial alloying elements could be verified successfully.
