Abstract

The deformation-enhanced atomic redistribution, i.e., accelerated ordering upon warm (573 K) and disordering upon cold (298 K) high pressure torsion, has been investigated using Mössbauer spectroscopy in the binary invar Fe_{100 –}_xNi_x (x = 34.2–35.5 at %) alloys. Results of deformation-induced ordering and high-energy electron irradiation have been compared.
