Today, shape-memory alloys have already taken their place in various fields of science and technology. The most used alloy is titanium nickel or nitinol. When manufacturing alloys based on NiTi in order to use them for various products, it is necessary to know the conditions, under which it is possible to obtain alloys with previously known parameters of the phase transformation. In the work, the dependence between the Ni/Ti ratio, preliminary thermomechanical treatment (TMT) and the temperature of the beginning of the martensitic transformation ($M_{s}$) is obtained.
Key words: direct and reverse transformations, shape-memory effect, vacuum induction melting, vacuum arc melting, additive methods.
