FIELD: metallurgy.
SUBSTANCE: liquid alloy is quenched, its composition being as follows in wt %: boron - 2.1-3.5, silicon - 2.0-4.5, nickel - 5.0-10.0, cobalt - 15.0-30.0, chromium - 12.0-20.0, iron and unavoidable impurities making the rest, provided the following terms are satisfied: sum of boron and silicon makes 4.5-7.0, while that of boron and nickel equals 7.5-13.0. Then, intensive plastic deformation by twisting is performed by quasihydrostatic pressure and temperature and ultrasound processing at 18.0-22.0 kHz are performed.
EFFECT: high hardness and saturation magnetisation at low coercive force.
