Abstract
Deformation-induced internal stresses in metallic glasses (MG) is one of the most important questions in the problem of adequate plastic flow description of these materials. Internal stresses arising at deformation define a strong worsening of MG soft magnetic properties after cold working. TEM-investigations of partially crystallized MG show long-range interaction of crystallites with shear band switch indicates the presence of long-range internal stress fields connected with shear bands. An analogous conclusion was drawn from the analysis of domain structure in deformed ferromagnetic MG. Deformation-induced internal stresses are particularly manifested in the anomalous stress relaxation, in the Bauschinger effect and in the strain recovery of predeformed samples. The present paper is devoted to determination of effective internal stresses arising at tension of a Co-based MG and to investigation of their temperature dependence.
