Multilayer Surface-Area Structure and the Influence of Residual Oxygen on its Formation During Irradiation of TiNi Alloy with a Low-Energy High-Current Electron Beam

The structure and phase composition of a subsurface layer of TiNi alloy modified in the mode of pulsed melting with a microsecond low-energy (to ~40 keV) high-current (to ~50 kA) electron beam is investigated. The influence of the number of pulses at a constant energy density on the characteristics...

Description
Summary:The structure and phase composition of a subsurface layer of TiNi alloy modified in the mode of pulsed melting with a microsecond low-energy (to ~40 keV) high-current (to ~50 kA) electron beam is investigated. The influence of the number of pulses at a constant energy density on the characteristics of structure, phasecomposition changes, and behavior of the phase distribution near the surface is considered. The role of oxygen in the columnar structure stabilization of the recrystallized surface layer is discussed.
