Abstract Scope |
Elementary deformation events (e.g. dislocation avalanches and twin nucleation/growth) are typically concealed in the deformation curves as they provide only average information due to the limited sensitivity and time resolution of deformation devices. On the other hand, supplementary techniques such as ultra-fast imaging and acoustic emission, if implemented correctly, allow for detailed characterization of the activity of deformation mechanisms. Here, we apply these techniques to characterize metallic materials ranging from microsamples to complex advanced bulk materials, focusing on the correlated (yet intermittent) behavior of plastic events. Using these techniques, spatial and temporal patterns in the seemingly random plastic events can be recognized by employing various statistical analyzes. The obtained data contribute to the fundamental understanding of deformation dynamics and can be utilized in designing future metallic materials. |
