Abstract
High-Entropy Alloys (HEAs) have higher mixing entropy than the conventional alloys and intermetallic compounds and form the stabile solid solutions with disordered structure. They exhibit unique and special properties, in particular high hardness, wearresistance, significantly high strength, structural stability, good corrosion, and oxidation-resistance. HEAs �exotic�, core effects are followings: high configurational entropy; sluggish diffusion; lattice distortion and cocktail effect. At the current stage, the volume of investigations towards high entropy materials extended from single-phase solid solution structure to multi-phase structures, containing solid solution phases, intermetallic compounds, oxides, borides etc. Promised direction in this field are the high-entropy composites, prepared based on the HEAs matrix- reinforced with hard ceramic compounds. Accordingly, there is a huge potential to find new properties in the field of multi-component high-entropy nanostructure materials. The Fe-W-Al-Ti-Ni�BC composition considered in article for fabrication of HEA�s. The content of elements in blend were determined on the base of phase diagrams available in scientific databases. The planetary ball mill is used for Mechanical Alloying (MA) and nanopowder production. Industrial explosives are used for shock wave generation and consolidation of the blend. The MA blend charged in low carbon cylindrical steel tube container and closed both sides. A cardboard box with blend container was filled with explosives and detonated. The phase analyses and structure-property of obtained bulks HEA compacts investigated. Results of investigations discussed and presented in the paper.
