"Temperatures of phase transformations and properties of the Ni-Ti and Ni-Ti-X based shape memory alloys are in the first place highly dependent on processing technology. At present, the Ni-Ti-(X) based alloys are mostly prepared in vacuum, and various methods of melting are used (electron-beam melting, arc melting, high-frequency induction melting). Another possibility for the preparation should be plasma melting. Complications during preparation are caused mainly by carbon, nitrogen and oxygen, which could form non-metallic inclusions. Due to titanium carbide formation in Ni-Ti matrix, the concentrations of nickel and titanium are shifted, so this leads to change of the temperature of martensitic transformation. Creation of a low-melting phase Ti2Ni, which causes a distinct susceptibility to hot formation of cracks, is another issue arising during melting of Ni-Ti alloys. The presented work is focused on comparison of individual methods of preparation of the alloys mentioned above."@en .
