A rather featureless shear step having formed meniscus with the upper part of the BMG specimen.
Waves (white arrows) on a shear step on BMG surface indicating liquid stages in its history. The waves do not cross lines (black arrows) on the surface indicating that the step formed in several stages.
Arrows show U-shaped meniscus locations at the step bottom indicating viscous behavior and high temperatures at the end of the shear event.
Serrations on a stress-strain curve of a Zr-based BMG.
Calculated temperature rise vs distance away from the shear band during formation of a micron-size shear step. When the step is required to form under positive local stress conditions , a thermal diffusion layer of approximately is found to heat to which melts all Zr-based metallic glasses.
