Abstract—The structure and properties of an 80-μm-thick ribbon made of high-entropy Al9.6Co12.5Cr12.2Fe39.4Ni24.3Mn2.0 alloy by ultrarapid quenching from melt have been studied. The alloy underwent ultrarapid quenching consists of bcc-Fe-based solid solution and the fcc Co0.8Cr0.8Fe0.8Mn0.8Ni0.8 phase. Under tensile loading, the deformation process becomes intermittent and stress-strain curves exhibit stress oscillations. It has been shown that strains estimated by the method of digital image correlation locally may nondestructively reach 1%, although the integral value of strain at failure does not exceed 0.5%. The deformation behavior of the thin ribbon made of high-entropy alloy has been analyzed at different structure-and-scale levels.
期刊介绍：
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
