Development of dislocation and domain structure in pd3fe alloy at various degrees of deformation and cooling rates during step annealing

Transmission electron microscopy was used to study the development features of dislocation and domain substructures of the Pd3Fe alloy in disordered and ordered states with a change in the strain value. The ordered state was obtained by annealing with a stepwise decrease in temperature at a rate of 5 or 10 deg / day. A different character of the dependence of the average scalar density of the dislocations and the curvature-torsion of the crystal lattice on the magnitude of deformation for the alloy in the disordered and ordered states and the correlation of this difference with the evolution of the dislocation substructure were established.
