Аннотация:The effect of high pressure torsion (НРТ) at 77 and 295 K on the phase composition of (FeCo)100-xVx (x = 0–6.0) soft magnetic alloys were studied by X-ray diffraction, transmission electron microscopy and magnetometry. It was established that HPT leads to the suppression of excess γ phase in the alloys containing 3.0–6.0% V. It was concluded that the observed effect by analogy with the TRIP effect is a consequence of the strain-induced γ→α martensitic transformation. It was found that the suppression of the paramagnetic γ-phase leads to a noticeable increase in the specific saturation magnetization.
