It was shown thatthere is a characteristic deformation temperature and a strain range, in which thecritical yield stress for stress-induced transformation acquires optimum matchingwith the yield strength of the β-Nb particles. In this case, deformation effectivelyincreases the transformation hysteresis, while the strain recovery ratio remains use-fully high. The martensite with irregular fine twin substructure and martensitecontaining some dislocations as well as martensite intersected by the β-Nb particlespossess high stability.
