... if the powder was milled. On the other hand, heat-treating the atomized powder before extrusion resulted in a significant increase in elongation to fracture (∼13%), albeit with a concomitant decrease of TYS by approximately 33 MPa. The greatest decreases in elongation to fracture and ultimate strength...

...Yong Huang; Mason Morehead Various methods for the production of bulk nanostructured (NS)/ultrafine-grained (UFG) materials have been developed, including equal channel angular extrusion (ECAE), a form of severe plastic deformation. Using an ECAE NS/UFG copper bar as an example, this study has...
