Abstract. In the presented paper the complex studies of microstructure and phase composition of the alloy before and after electrochemical corrosion tests in solutions of 1M HCl, 3M HCl, 1M H2SO4, 3M H2SO4 have been carried out. The studies showed that the corrosion process in the alloy Ti49.1Ni50.9 in the case of electrochemical corrosion took place on all samples and in all solutions in the form of appearance of pittings, as well as with corrosion products when tested in H2SO4 solutions with different concentrations, in the case of 3 M HCl corrosion products were also found on the surface of the samples. A change in microstructure character was found in the coarse grained state in 3 M solutions, while no such change was found in the ultrafine grained state.
Keywords: TiNi alloys, coarse-grained and ultrafine-grained structure, electrochemical corrosion, acid solutions, phase composition
