Abstract

<jats:p><jats:italic>In situ</jats:italic> straining transmission electron microscopy (TEM) experiments were performed to study the propagation of the shear bands in the Zr<jats:sub>56.3</jats:sub>Ti<jats:sub>13.8</jats:sub>Cu<jats:sub>6.9</jats:sub>Ni<jats:sub>5.6</jats:sub>Nb<jats:sub>5.0</jats:sub>Be<jats:sub>12.5</jats:sub> bulk metallic glass based composite. Contrast in TEM images produced by shear bands in metallic glass and quantitative parameters of the shear bands were analyzed. It was determined that, at a large amount of shear in the glass, the localization of deformation occurs in the crystalline phase, where formation of dislocations within the narrow bands are observed.</jats:p>
