METHOD OF PRODUCING CYLINDRICAL WORKPIECES FROM MEDIUM-ENTROPY ALLOY FeMnCoCrC Russian patent published in 2025 - IPC C21D1/02 C21D7/02 C21D8/06 B21J1/02 C22C30/00 C22C38/04 

FIELD: metallurgy; performing operations.

SUBSTANCE: invention relates to metallurgy, in particular to methods of producing hardened cylindrical billets from medium-entropy alloys of austenitic class. Method of producing cylindrical workpieces from medium-entropy alloy Fe_49.5Mn₃₀Co₁₀Cr₁₀C_0.5 includes quenching of workpieces by heating to 1,050 °C, holding for 2 hours with cooling in water, cold plastic deformation by radial forging to degree of deformation of 85-90% at room temperature and subsequent heat treatment with cooling in air. Heat treatment after deformation of workpieces is carried out by annealing at 600 °C and holding for 10 minutes.

EFFECT: disclosed is a method of producing hardened cylindrical workpieces from medium-entropy alloys of austenitic class.
