摘要: Flow serrations recorded during inhomogeneous deformation of Zr52.5Ti5Cu17.9Ni14.6Al10 (Vit105) were studied compression testing at temperatures between −40 and 60 °C. The shear band velocities determined exhibit a pronounced temperature dependence covering nearly two orders magnitude. follow an Arrhenius-type behavior with associated activation energy 0.3±0.05 eV. results demonstrate thermally activated mechanism propagation, which is similar to the other, nonmetallic amorphous materials.
