Abstract
Strain recovery of melt spun metallic glasses Fe84B16 and Ni77.5Si7.5B15 predeformed by tensile creep at temperatures 453 <T <633 K has been investigated. The determined kinetic recovery law allowed to propose and verify a model of strain recovery as a result of reversible atomic rearrangements in the two-well relaxation centers with a small asymmetry of the potential. The model is shown to explain the main strain recovery regularities. An inter-relationship between reversible and irreversible components of structural relaxation of metallic glasses is discussed.
