Control of mechanical properties of a high-entropy alloy Cantor CoCrFeMnNi

A brief analysis of the work on changing mechanical properties high-energy alloy (HEA) Cantor CoCrFeMnNi in various ways has been performed. The article describes influence alloying with aluminum, vanadium, manganese, titanium, silicon, carbon, copper hardening wind turbines obtained by vacuum arc melting, laser melting and drip casting, subsequent plasma sintering, gas sputtering followed shock wave static compaction. It is shown that additives 2.5 % TiC 5 WC significantly improve tensile strength, but reduce elongation to failure. effect grain size range 4.4 – 155 µm increase strength a decrease size. Lowering temperature increases yield limits for grains all sizes. Intensive plastic deformation forming nanoscale (~50 nm) up 1950 MPa hardness 520 HV. Subsequent isochronous isothermal annealing allows varying ductility turbines. formation nanostructured-phase states during compounding, spark at room temperature, maintaining excellent plasticity (elongation approximately 28 %). As one methods modifying turbines, authors propose electron-beam processing (EPO). curves turbine, technology wire-arc additive production, after EPO an electron beam energy density 10 30 J/cm 2 , carried out; assumptions about reasons characteristics have found substantiated. comparative turbine was out, discrepancy values parameters were noted.
