In the work, we study the mechanisms of structural phase state formation in NiTi surface layers after lowenergy pulsed electron beam irradiation depending on the electron beam energy density. It is revealed that after electron beam treatment of the NiTi specimens at energy densities E1 = 15 J/cm2, E2 = 20 J/cm2, and E3 = 30 J/cm2, a series of effects is observed: The absence of the Ti2Ni phase and the presence of new peaks correspond to the B19′ martensite phase with monoclinic structure. Estimation of the relative volume content of the B2 and B19′ phases from the total intensity of their peaks shows that the percentage of the martensite phase increases from ∼5 vol.% in the NiTi specimen irradiated at E1 = 15 J/cm2 to ∼80 vol.% in the NiTi specimen irradiated at E3 = 30 J/cm2. It is found that in the NiTi specimens irradiated at E ≤ 20 J/cm2, the layer that contains a martensite phase resides not on the surface but at some depth from it.
