Abstract

The new technique of estimation of cracking resistance and ability to plastic flow of metallic glasses on the basis of iron and cobalt is presented at microindentation of tape samples. The crack resistance (K_1c), density of zones of plastic deformation (ρ) and their average length (L) were calculated as physicomechanical criteria. The behavior of these characteristics depending on annealing temperature and chemical composition was established. The received results are discussed from positions of the structural transformations realized at thermal treatment of studied metallic glasses.
