Abstract

The effects of high pressure torsion at 77 and 295 K on the phase composition of soft magnetic alloys (FeCo)100-xVx (x = 0-6.0) were studied by X-ray structure analysis, transmission electron microscopy and magnetometry. It was established that HPT leads to the suppression of excess γ-phase in alloys containing 3.0-6.0% V. It was concluded that the observed effect was a consequence of the martensitic transformation γ→, due to deformation, along the lines of TRIP effect. It was established that suppression of the paramagnetic γ-phase leads to a noticeable increase in the specific magnetism of saturation.
