| Abstract Scope |
In the integrated computational materials engineering (ICME) roadmap, quantitative correlation of the material microstructure and its mechanical deformation properties by using a multiscale modeling approach is of high interest for material production and component forming industry. In this study, we present a multiscale characterization and modeling approach to incorporate the influences of the microstructural features on the mechanical properties including plasticity, damage, and ductile fracture behavior. Both micro and macro scale experiments and simulation are conducted to describe and interpret the deformation and failure behavior. The anisotropic flow behavior under various strain rates is correlated with the microstructure features and their evolution during deformation, while the macroscopic damage/fracture behavior is also interpreted by the microstructural-level mechanisms in the mesoscale simulation. After validation of the model, we show the potential of the approach for the microstructure design toward a high-strength and damage-tolerant steel development. |
