| Outline of Final Research Achievements |
In this study, anomalous temperature dependence of pseudoelasticity in a β-titanium alloy, was investigated from a standpoint of small particles of the ω phase in the matrix, and in terms of phase stability.
It was revealed that (1) the martensite was not formed by cooling at -260℃ without stress and (2) the matrix transformed to the martensite and the ω phase disappeared when exposed to stress.
