An analysis of plausible crystal structures of R-phase and precursory structures in Ti-Ni based on solely kinematical data on presence and equivalence of extra-reflections of diffraction patterns, as well as further data on symmetry of structure was carried out. A character of possible ordering and displacements, required to form these phases from parent BCC lattice, was determined. A classification of possible structures was given.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
