সংক্ষিপ্ত:	Title screen The special features inherent in the formation of the structural-phase states on the surface of titanium nickelide samples subjected to multiple low-energy high-current variable energy density pulsed electron beam irradiation are investigated. The parameters of the electron beam operated in the fivefold surface melting regime are as follows: pulse duration t = 150 s, current I = 70 А, and energy densities Е 1, Е 2, and E 3 = 15, 20, and 30 J/сm2, respectively. The surface layer structure was examined by methods of the x-ray diffraction analysis and transmission electron microscopy. It is found that in the irradiated TiNi samples with Е 20 J/сm2, the layer containing a martensite phase lies at a certain depth below the surface rather than on the surface. In the irradiated TiNi sample with E 3 = 30 J/сm2, the subsurface region is in a two-phase state (B2 + B19), with the В19? phase being predominant. It appears that the lower is the energy density, the smaller is the amount of the martensite phase. Режим доступа: по договору с организацией-держателем ресурса
