Abstract Scope |
Microscopic strain localization is a key process determining various mechanical properties of metallic materials, including formability. In this study, we compare the microscopic strain localization patterns of various single-phase and multi-phase alloys with very different matrix crystal structures (fcc, bct, hcp, bcc+hcp, etc.), textures, grain sizes, and properties. We observe that the strain localization patterns are interestingly similar regardless of these variations in crystal structure and properties. This observation supports the recent proposal that the statistical distribution of local strain in various steels follows a universal law, i.e., a lognormal distribution. It also enables the use of a simple skewness parameter to quantitatively describe the heterogeneity of strain localization. |
