| Abstract Scope |
Deformation-induced microstructural strain localization is a key process determining various mechanical properties of metallic materials, including formability. However, due to the complexity of the strain localization patterns, most studies investigate this phenomena qualitatively. Recently it was shown that the statistical distribution of local strain in various steels follow a universal law, i.e., a lognormal distribution. To understand this behavior further, we performed a statistic study of strain localization in various single phase and multi-phase alloys. Based on these observations, we propose a parameter to describe the statistical distribution of localized strain. Furthermore, as the loss of viable facets at high deformation levels handicaps this approach, we propose a "stitching" method, that enables the investigation of strain localization at later stages of deformation, even up to fracture. |
