NiTi-based alloys belong to progressive materials which exhibit so called a shape memory phenomenon. These alloys are frequently used at high-temperature applications and automotive industry. Structurally complex phase analysis of TiNi-based alloys was carried out. The chemical composition of the prepared alloy was 49.5Ni-25.5Ti-10Zr-15Nb (at.%). The alloy was prepared by a vacuum induction melting with gravity casting and examined by methods of optical microscopy, scanned electron microscopy, X-ray diffraction and thermo-evolution method of interstitial element analysis.Keywords: NiTi Alloy, vacuum induction melting, scanned electron microscopy
