"Intermetallic compound containing approx. 50 at. % Ni and 50 at. % Ti is considered to be a standard shape memory alloy. The basic requirement to metallurgy of these advanced materials is strict adherence to chemical composition of the alloy, which is the main condition for obtaining of the alloy with the required transformation temperatures. These alloys are most commonly prepared by plasma melting or vacuum induction melting. The technology of preparation of the alloys have significant effect on microstructure of prepared alloy. For successful use it is necessary to obtain homogenous microstructure. After preparation in graphite crucible, microstructure often contains undesirable particles as TiC and Ti4Ni2O. This article deals with preparation of Ni-Ti shape memory alloys in relation to the microstructure. Observation of microstructures was realized by light microscopy, electron microscopy and transmission electron microscopy."@en . "St. Petersburg State Mining Institute" . . . .
