Observation of Instabilities during Plastic Deformation by in‐situ SEM Indentation Experiments

This communication presents results on the observation of pop‐ins and shear band formation during indentation in a Zr‐based bulk metallic glass (Vitreloy‐105). The focus is on in‐situ SEM experiments using a recently developed miniaturized instrumented indentation system that can be used inside the SEM chamber. Using frames from a video sequence, a partial correlation between displacement bursts in the load‐displacement curve and shear band activity at the specimen surface could be established for the first time.
