| Description
| - For production of Ti-Ni based alloys are mostly used the cleanest raw materials. The typical input materials for preparing the alloys are a titanium sponge (pure titanium rods) and metallic nickel (pellets, piece electrolytic, etc.). Ni usually has lower contents of interstitial impurities. The titanium sponge may on the other hand contain up to 400 - 800 ppm of oxygen and circa 25 - 80 ppm of carbon. The current key technologies of the preparation of alloys of the Ni-Ti-(Me) system are most often realized in a vacuum. Here several methods are used (melting by electron beam – EMB, vacuum arc melting – VAR, high-frequency induction vacuum melting in graphite crucibles – VIM. Plasma melting represents another possible technology. The properties of these alloys (both shape memory and mechanical) are significantly affected by the contents of these elements, similarly to other materials. The degradation of properties is also affected by the quality of the surface and the presence of hydrogen. This article deals with examination of possibilities of Ti-Ni alloys recycling using older alloys prepared and used before. There are also discussed differences between new prepared alloys (from raw materials) and alloys recycled with respect to gas and other impurities contents. Microstructures were evaluated by OM and SEM techniques. For melting was used vacuum induction furnace with graphite crucible and centrifugal casting into rods with diameter 20 mm, length 225 mm.
