Effect of Large Plastic Deformations in a Bridgman Chamber on the Structure and Properties of FeCo–V Alloys

Abstract

Aspects of the structural formation and properties of (FeCo)_100−xVx alloys (x = 0; 1.5; 3.0; 4.5; 6.0) after torsion under high hydrostatic pressure in a Bridgman chamber at different temperatures (77 and 295 K) and different numbers of revolutions of the movable anvil (from 0.5 to 6) are investigated via X‑ray diffraction analysis and transmission electron microscopy, and by measuring microhardness and coercive force. The effect composition, temperature, and plastic deformation have on the volume ratio and average size of deformation fragments and dynamically recrystallized grains is established using a two-phase mixture model.
