Abstrakt: Abstract—The structure, the phase composition, the physicomechanical properties, and the corrosion resistance of a precipitation-hardened composite material fabricated by hot pressing (1050°C, 30 MPa, 30 min) of powders of high-alloy ferritic steel (Fe base alloy, 30% Cr, 0.2% C) and molybdenum in an amount of 1, 5, and 10% are studied. The maximum compressive strength (1815 ± 3 MPa) is characteristic of the composite material with 10% Mo. After quenching from 1050°C, the composite material (Fe–Cr–Mo) has no χ phase, its strength decreases to 1656 ± 21 MPa, and the residual deformation (shortening) increases by 2.5–3 times.
