Abstract Scope |
Microstructure evolution during plastic deformation is a complex phenomenon controlled by myriad processes. Multimodal characterization approaches can provide the high-fidelity data required to make accurate predictive models of material response. In this work, we present 3D characterization of a wrought sample of Al 2219 both before and after macroscopic deformation. By combining non-destructive methods like diffraction contrast tomography (DCT) with serial sectioning within an electron microscope using the TriBeam system, 3D reconstructions of grain structure and orientation can be captured at multiple stages of the deformation process, providing insight into microstructural evolution and damage accumulation in a wrought Al alloy. Details of the reconstruction process and the opportunities for multimodal data fusion will be presented. The application of these data to crystal plasticity modeling will also be discussed. |
