| Abstract Scope |
Ductile fracture is an inherently multiscale processes, ranging from nanoscale crack nucleation mechanisms to collective dislocation interactions ranging across hundreds of microns. Understanding these processes requires multiscale characterization approaches that reflect the nature of the processes. A key factor in these multiscale approaches is the ability to quantify data in such a way that information can be passed between the length scales. In this talk, I will discuss the application of multiscale electron microscopy techniques to understanding fracture in Al 6xxx alloys under different loading conditions. Heat treatable Al alloys provide an especially interesting case study as they are composed of a range of secondary particles, including distributed intermetallic particles, dispersoids on the order of single microns, and precipitates, as well as heterogeneities inherent to polycrystalline materials. Results will be discussed in terms of ductile fracture processes and the general applicability of multiscale electron microscopy to understanding deformation and failure. |
