Описаны технологии и оборудование электронно-лучевого послойного получения металлических изделий как из проволоки, так и из порошка. Приведены экспериментальные данные, полученные авторами в результате электронно-лучевого аддитивного изготовления образцов из низкоуглеродистой стали, нержавеющей аустенитной стали и технического титана. По- лучены зависимости геометрических параметров наплавляемого слоя от основных параметров электронного луча, а также схема изменения профиля одиночного слоя наплавки от тока луча. Проведен анализ микроструктур. Описаны основные характерные зоны, образующиеся в образцах, полученных данным методом. Показано, что при работе с нержавеющей сталью типичная микроструктура образцов – крупные дендриты с главными осями длиной до нескольких миллиметров в направлении теплоотвода. Однако было замечено, что в участках, претерпевших повторный многократный переплав во время наплавки последующих слоев металла, происходит рекристаллизация и образуются равноосные зерна. В технически чистом титане помимо характерной крупнозернистой (до нескольких миллиметров в диаметре) структуры существуют зоны, где наблюдается пластинчатая структура с колониями около 1 мм, а также зона в виде полосы шириной около 1 мм вдоль стенок, представляющая собой игольчатую структуру. Это, очевидно, связано с режимом охлаждения, так как характер теплоотвода по краям заготовки отличается от центральных зон. Проведен анализ перспектив развития электронно-лучевых аддитивных технологий. Продемонстрированы примеры использования электронно-лучевой аддитивной технологии в современном производстве ускорительной техники, авиа- и машиностроении.</p></abstract><trans-abstract xml:lang="en"><p>General information about development of additive technologies, as well as an overview of the main schema- tics of layer by layer manufacturing of metal products is presented. The technologies and equipment for electron beam layerby-layer production of metal products using wire and powder as a raw material is described. Experimental data obtained by the authors as a result of electron beam additive manufacturing of low-carbon steel, stainless austenitic steel and technical titanium samples are described. Relations between the product geometry and the electron beam main parameters are obtained. The analysis of microstructures is carried out. The main zones formed in the samples fabricated by this method are described. It is shown that typical microstructure of stainless steel samples consists of the large dendrites with main axes up to a few millimeters in the direction of heat sink. In a pure titanium, in addition to the characteristic coarse-grained (up to several millimeters in diameter) structure, there are zones where a lamellar structure with colonies of about 1 mm is observed, as well as a zone in the form of a strip about 1 mm wide along the walls, which is an acicular structure. This is obviously related to the cooling mode, since the character of the heat sink along the edges of the sample differs from the central zones. The analysis of electron beam additive technologies prospects is carried out. Examples of electron beam additive technology using in modern fabrication of accelerator technics, aircraft and machine building are demonstrated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аддитивные технологии</kwd><kwd>электронно-лучевые технологии</kwd><kwd>микроструктура</kwd><kwd>титан</kwd><kwd>нержавеющая сталь</kwd></kwd-group><kwd-group xml:lang="en"><kwd>additive technologies</kwd><kwd>electron beam technologies</kwd><kwd>microstructure</kwd><kwd>titan</kwd><kwd>stainless steel</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Frazier, W.
