Abstract

Abstract—The results of a comparative analysis of the structure of Ti2NiCu alloy subjected to severe plastic deformation by high pressure torsion (HPT) and subsequent annealing are presented. The study of the structure was carried out by diffractometry of electron, X-rays and neutrons, transmission electron microscopy. It is established that an amorphous-crystalline state is formed in the alloy: nanocrystallites with a B2 lattice are present in the amorphous matrix. The analysis of diffuse maxima showed that the topological and compositional near atomic order of nanodomains with a superstructure ordered by type B2 and L21 is present in the Ti2NiCu alloy after HTP on 5 rev.
