- Abstract
The paper presents the results of a comparative analysis of the structure of Ti2NiCu alloy subjected to severe plastic deformation by high pressure torsion and subsequent annealing. The structure of the alloy was studied using diffractometry, electron microscopy, X-ray and neutron techniques, as well as transmission electron microscopy. The analysis has revealed the formation of an amorphous-crystalline state within the alloy, with B2-lattice nanocrystallites present in the amorphous matrix. The analysis of diffuse maxima has indicated that the Ti2NiCu alloy, after subjecting to high pressure torsions till five turns, possesses topological and compositional short-range order in the form of nanodomains with a superstructure arranged by B2 and L21 order.
