Abstract
The effects of high pressure working and low temperature annealing on the structure and microhardness of Fe-, FeNi- and Co-based metallic glasses have been investigated. The possibility of strengthening has been found for both binary and multicomponent metallic glasses. The behaviour of the microhardness dependence on the applied pressure, with a microhardness maximum at 3–5 GPa, and the behaviour of the microhardness dependence on the temperature of annealing, with two maxima, are discussed in terms of rearrangements of structural defects in metallic glasses. A certain similarity of high pressure working and low temperature annealing effects on the structure and microhardness of metallic glasses has been found.
