  journal article in Scopus
  The weldability of advanced heat resistant ODS metallic materials in combination with conventional materials is a prior requirement for their wider use in energy production. The microstructure of ODS steels is composed of alpha iron based matrix with dispersed oxide particles. Due to heating during conventional welding, the microstructure and properties of the resulting weld joints are affected and the joints often become the weakest point of the structure. The electron beam welding with its reduced heat affected zone size may be an answer in this. The presented article is focused on thorough metallographic evaluation of the structure of heterogeneous electron beam welds which combine stabilized austenitic stainless steel with the MA956 ferritic ODS steel. EB welded joints were evaluated by light and analytical electron microscopy including EDS and phase EBSD analyses in the as-welded state and after post-weld heat treatment. Mechanical properties of the weld were evaluated from the results of micro hardness profiles. Achieving an appropriate structure of such welds and correct welding parameters are crucial aspects for future successful application of similar joints in energy industry

  Bi-metallic mixtures of elemental powders were deposited by cold spray technique in the form of bulk, self-supportive deposits with thickness of about 8 mm. The combinations used were Ti–Al, Fe–Al and Ni–Al in 1:1 at.% composition. Aluminides of titanium, iron and nickel draw substantial attention as materials with high application potential but also substantial production technology complications. Therefore the bi-metallic deposits were subjected to extensive series of annealing experiments in order to assess their behaviour during reaction diffusion synthesis of intermetallic phases. Short annealing for 2 h was used in 4.8 Argon protective atmosphere. Metastable and according to PD stable phases were identified alongside with heterogeneous diffusion artefacts (e.g. porosity). Temperatures ranging from 350 °C to 600 °C were used, which provided both solid-state reactions and diffusion in locally melted aluminium part of the bi-metallic deposit.
