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 vo...

On the base of unsaturated polyester resin and nano powder fillers, polymer concrete (PC) was produced applicative in aggressive underground conditions. The curing agents of the resin for the polyester resin were Akcobalt 6% (cobalt 2-ethylhexanoate mixture) and Akperox A1 (Methyl Ethyl Ketone Peroxide-MEKP). Ultrafine powder was produced by grinding of a coarse mixture on the PULVERISETTE 7 premium Line planetary mill by a dry method. Selection and designation of concentrations of aggressive media - sodium sulfat...
