Abstract Scope |
High resolution microstructure data is readily available and has opened the doorway to understanding processing-structure-property relationships. Inconsistent data representations and an inability to quantitatively compare microstructures across material classes prevent the construction of a general materials database though, and a general microstructure representation and comparison methodology would significantly further the agenda of ICME.
We present a standard representation of polycrystalline microstructures that enables quantitative microstructure comparison while accounting for inherent microstructure variability. The basis of the framework is the idea of a microstructure state space, with points in the space corresponding to probability distributions of characteristic micrograph volume elements (windows). A morphological distance between windows is developed and used to find the intrinsic geometry of a point cloud of windows sampled from a given microstructure. This is used to develop a pseudo-metric between microstructures that enables queries into a prototype database containing microstructures with highly variable grain geometries. |
