The selected mode of obtaining a porous TiNi-based alloy with the addition of 5 and 10 at. %o Ti is characterized by the formation of moderate and increased portions of the liquid phase, respectively. Getting alloy with 15 at. % Ti with a regular porous structure is impossible due to the formation of an excess melt volume during sintering. The data of X-ray diffraction analysis of porous TiNi-based alloy show that the alloy contains an austenitic TiNi (B2) phase, martensitic TiNi (B19’), as well as secondary phases Ti2Ni, Ti3Ni4 and traces of the TiNi3 phase. The use of the Ti additives considered allowed us to solve the problem of correcting the atomic composition of the TiNi compound.
