In this work, we study the effect of electron-beam treatment on the structural features of the TiNi powder alloy obtained by calcium hydride reduction. Experimental two-dimensional porous samples based on TiNi powder alloy were obtained by diffusion sintering to use non-destructive methods to study their structural features. It has been established that electron-beam treatment leads to homogenization of the phase-chemical composition of the surface layer of the TiNi powder alloy, smoothing of the surface relief of TiNi powder particles, and healing of defects on their surface. Energy-dispersive X-ray spectral microanalysis showed that the concentration of Ti increases in the surface layer. This is due to the recrystallization of this layer containing particles of Ti2N and Ti4Ni2(O, N, C) during its remelting under the action of a high energy density of the electron beam during processing.
