Influence of severe plastic deformations in the bridgman anvil on lattice parameters and microhardness of ferromagnetic metals

Abstract

The influence of severe plastic deformation by torsion in the Bridgman anvil on the lattice parameters of pure ferromagnetic metals Ni and Co is investigated by x-ray diffraction analysis. It is shown that torsion combined with strong compression leads to decrease in the lattice of these metals and to the change in the level of crystal lattice microstrains. The mechanisms of deformation influence on the lattice parameters are proposed.
