Recent developments in the processing and properties of ultrafine-grained materials
Abstract
Ultrafine-grained (UFG) materials have grain sizes within the submicrometer or nanometer range and they are prepared through the application of severe plastic deformation using processing techniques such as equal-channel angular pressing or high-pressure torsion. This report describes recent developments in interpreting the properties of these UFG materials including evaluating the paradox of high strength and low ductility and examining the potential for developing a weakening effect in some materials.
