Crystallographic Textures Produced During Sand Blasting

Evolution of crystallographic textures in sand blasted surfaces is studied. Sand blasting is approximated as a series of ideal cylindrical, flat punch and wedge indents. Features of the deformation field produced during indentation with these geometries is studied using in-situ techniques. Subsequently, crystallographic textures produced during indentation with these geometries is delineated using orientation imaging microscopy and simulated using the visco plastic self consistent framework. Finally, using a novel heuristic, the crystallographic textures created during indentation are related to those produced during sand blasting. It was seen that the heuristic is able perform a first order replication of empirically observed crystallographic textures.
