The short-range clustering in Fe–Cr alloys enhanced by severe plastic deformation and electron irradiation

ABSTRACT

The short-range clustering enhanced by migration of non-equilibrium point defects generated under the high-pressure torsion in Bridgman anvils and ball milling is detected by means of Mössbauer spectroscopy in Fe_100−cCr_c (c = 12–20.6) binary alloys. The degree of short-range clustering is increased with increasing the temperature of severe plastic deformation. The short-range clustering enhanced by severe plastic deformation is similar to that obtained after the thermal annealing and electron irradiation at close temperatures.
