Materials processing by simple shear
TL;DR: In this paper, simple shear can be considered a "near ideal" deformation method for structure and texture formation in metal-working, and the unusual effects that are observed in both the structure and physical-mechanical properties of various metals and alloys suggest many new applications of the simple Shear method in materials synthesis and processing.
