Short-Range Atomic Ordering Accelerated by Severe Plastic Deformation in FCC Invar Fe-Ni Alloys

摘要

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 Mossbauer spectroscopy in the binary invar Fe100 -xNix (x = 34.2-35.5 at %) alloys. Results of deformation-induced ordering and high-energy electron irradiation have been compared.
