The long-term operation of rails has been studied with focus on (1) the formation and behavior of structural-phase states and nanoscale structures, (2) the modelling of the processes occurring in the surface layers of rails under severe plastic deformation and (3) the methods and techniques for assessing the structural and phase states of rails, internal stresses, and their evolution during the life cycle. The book references 264 original resources and includes their direct web link for in-depth reading.

ProsPects for the aPPlication of surface treatMent of alloys By electron BeaMs in state-of-the-art technologies recent papers on the application of intense pulsed electron beams for surface treatment of metals, alloys, metalloceramic and ceramic materials are reviewed. The advantages of pulsed electron beam application as compared with laser beams, plasma flows, ion beams are mentioned. Promising trends of the electron-beam processing application are analysed: (1) the surface smoothing, the elimination of surface microcracks with simultaneous change in structural-phase state of the surface layer for creating the high production technologies of finishing treatment of critical metal products of intricate shape from Ti-6Al-4V alloy and titanium, steels of different classes, WC-10 wt.% Co hard alloy, aluminium; (2) the removal of microburrs being formed in manufacturing of precision moulds (SKD11 steel) and biomedical materials (Ti-6Al-4V alloy); (3) the finishing surface treatment of moulds and dies; (4) the improvement of functional properties of metallic biomaterials: stainless steel, titanium and its alloys, the titanium-nickelide-based alloys possessing the shape memory effect, magnesium alloys; (5) the treatment of medical materials and implants; (6) the formation of surface alloys for powerful electrodynamic systems; (7) the improvement of characteristics of aircraft engine and compressor blades; (8) the formation of thermobarrier coatings being applied to combustionchamber surface; (9) the increase in fatigue service life of steels and alloys; (10) the hardening of rails' tread surface. As shown, at a correct selection of process parame
