SCIENTIFIC-TECHNICAL SECTION

Govorun Т. P., Lyubich А. I., Belous Е. А. — Effect of titanium, carbon and manganese on the properties of the metal deposit

Developed welding metal having martensite structure witch inclusions of carbides of titanium provides high wearing and can successfully be applied for welding of details working in conditions of abrasive wear process.
Key words: abrasive wear, titanium carbide, martensite structure, wear resistance

Gudenko А. V., Sliva А. P., Dragunov V. K., Shcherbakov А. V. — Features of the product formation by the electron beam deposition method

Electron beam deposition is a process that involves the use of an electron beam as a source of energy and wire as a raw material for the fabrication of metal products with complex shape in a vacuum and is part of the promising additive technologies group. In this paper a methodology for determining the electron-beam deposition regimes of a wire by the example of corrosion-resistant austenitic steel ANSI 316L is proposed. The proposed calculation methodology connects the main parameters of the process: the electron beam current, the addition wire feed rate, the movement speed of the electron gun and the dimensions of the deposited rollers. The investigation results of the microstructure and properties of the deposited metal are presented. Examples of the obtained cylindrical and conical products are adduced.
Key words: electron beam deposition, deposited wire, corrosion-resistant austenitic steel, deposition rate, microstructure of deposited metal

Shiganov I. N., Misyurov А. I., Smirnova N. А., Usov S. V. — Increase of mechanical characteristics of titanium alloy VT3-1 by local laser impact treatment

The paper discusses the effect of local laser treatment of Titus is a new alloy on the mechanical properties of the material and welded joints. To study the variation of hardness of the machined surface of titanium alloy VT3-1, depending on the processing parameters of pulsed laser radiation. It is shown that if the surface heat treatment the hardness can be increased relative to the base material 2—3 times. To reduce the content material of titanium nitride it is necessary to apply protection treatment zone with argon. Application of laser shock wave treatment also increases surface hardness, but it creates compressive stresses on the surface of the part, which can favorably affect the fatigue characteristics.
Key words: laser, titanium alloy, heat treatment, vol-new shock treatment, hardness
