... the solutionized Ti-50.9 at percent Ni material is 18 degrees above A f and the solutionized Ti-51.5 at percent Ni material is more than 100 degrees above A f . Aside from elastic deformation, it is discovered that dislocation motion and a reversible stress-induced martensitic transformation influence the micro...

...O. M. L. Yahya; M. Aubertin The mechanical behavior of different types of polycrystalline materials shows many common features in the ductile inelastic flow regime. It is typically controlled by dislocations motion, which involves the competitive action of hardening and recovery processes...
