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 ters, such as (i) accelerating voltage, (ii) energy density of electron beam, (iii) pulse number, and (iv) pulse length, it is possible to control thoroughly and/or to ma-nipulate the characteristics of structural-phase state and properties of surface. As noted, the important factor for improvement of the material properties and service duration of devices manufactured from it, there is the modification of structure in order to form a submicro- and nanosize grain (or subgrain) structure.

期刊介绍： The review journal Uspehi Fiziki Metallov (abbreviated key-title: Usp. Fiz. Met.) was founded in 2000. In 2018, the journal officially obtained parallel title Progress in Physics of Metals (abbreviated title — Prog. Phys. Met.). The journal publishes articles (that has not been published nowhere earlier and are not being considered for publication elsewhere) comprising reviews of experimental and theoretical results in physics and technology of metals, alloys, compounds, and materials that possess metallic properties; reviews on monographs, information about conferences, seminars; data on the history of metal physics; advertising of new technologies, materials and devices. Scope of the Journal: Electronic Structure, Electrical, Magnetic and Optical Properties; Interactions of Radiation and Particles with Solids and Liquids; Structure and Properties of Amorphous Solids and Liquids; Defects and Dynamics of Crystal Structure; Mechanical, Thermal and Kinetic Properties; Phase Equilibria and Transformations; Interphase Boundaries, Metal Surfaces and Films; Structure and Properties of Nanoscale and Mesoscopic Materials; Treatment of Metallic Materials and Its Effects on Microstructure and Properties.
