The surface region multilayer structure and the residual oxygen effect on its formation during the TiNi alloy processing with a low-energy high-current electron beam
The structure and phase composition of the surface TiNi layer modified by pulsed low-energy (up to ~ 40 keV) high-current (up to ~ 50 kA) microsecond electron beam were investigated. The effect of the number of electron beam pulses at a constant energy density on the structure characteristics, phase composition and phase distributions near the surface was considered. The influence of oxygen on the stabilization of the columnar structure in the rapidly solidified surface layer was discussed.
