Experiments were carried out to develop methods of diffusion welding of joints between single-crystal molybdenum and polycrystalline molybdenum through a titanium interlayer in the hot isostatic pressing (HIP) conditions. The structure and the mechanical and physical properties of the diffusion welded joints Mosingle + Ti + Mopoly were investigated. Composite molybdenum single-crystal mirrors with areas of 5000 and 8000 mm2 were produced and subjected to successful tests. © 2017 Informa UK Limited, trading as Taylor & Francis Group.

The results of investigations of the weldability of industrial beryllium are presented. The characteristic defects in the welded joints are described. The relationship between the content of the impurities and the susceptibility to formation of longitudinal and transverse cracks is analysed. Special requirements on the welding parameters and the content of the impurities for the manufacture of leak-tight welded sections are discussed. The possibility of producing high-quality welded joints in beryllium using filler materials made of aluminium alloys is justified and confirmed. The experimental results show that the welded joints in beryllium, produced without the filler material, are characterized by very low plasticity with a strength of approximately 50% of the strength of the parent metal. The strength of welded joints in beryllium, produced using aluminium filler materials, was equal to 70% of the strength of the parent material with high ductility. © 2014, © 2014 Taylor & Francis.

The preparation of the procurement activities for the ITER plasma-facing-components (PFC) is currently well underway. Three ITER procurement packages associated with PFCs are currently allocated to the Russian Federation (RF): delivery of the central assembly of the divertor (dome and reflector plates assemblies), delivery of 40% of the first-wall (FW) panels and high heat flux testing of divertor components during the qualification and subsequent manufacturing phases. The results of the qualification process for these tasks undertaken by RF industry are presented. Qualification mockups of the dome divertor structure were successfully manufactured in accordance with the ITER specifications and tested at heat fluxes exceeding operational ones. The maturity and reliability of the proposed design and manufacturing technologies, proposed by RF industry, was therefore demonstrated. To confirm the manufacturing readiness of technologies proposed for the fabrication of the ITER first wall, three qualification mockups were fabricated. Two were heat flux tested in two facilities abroad. In addition to launching the qualification process, the PFC team at Efremov Institute is preparing the industrial facilities for serial production of above mentioned components. A brief description of such facilities is presented in this paper, together with the manufacturing technologies to be used. Two electron beam facilities (Tsefey and IDTF) for various high heat flux testing of PFC components are also described. © 2011 Elsevier B.V. All Rights Reserved.
