| Abstract Scope |
Owing to the complexity of the mechanical response of Dual Phase (DP) steels, steel makers rely largely on experiments and trial-and-error approaches to develop new lines with higher strength and ductility in order to enable light weighting of automotive parts. Crucially, the flow and failure behaviors are intimately linked to the morphology of the microstructure. This paper presents an approach that use morphological features to predict the flow and failure behavior of DP Steels. We exploit phenomenological models to connect the deformation and failure at the microscopic level to the average mechanical response. Using basic microstructural features and flow behavior of the ferrite and martensite phases, the flow and failure behavior of DP Steels is estimated. Comparisons with macroscopic stress-strain response and in-situ tensile data for a DP steel shows that the model estimates local as well as global flow and failure properties and is an effective microstructure design tool. |
