TL;DR: In this paper, the authors defined severe plastic deformation (SPD) as metal forming processes in which a very large plastic strain is imposed on a bulk process in order to make an ultra-fine grained metal.
Journal ArticleDOI
Simultaneously Increasing the Ductility and Strength of Nanostructured Alloys
TL;DR: In this article, the authors reported a strategy to simultaneously increase the ductility and strength of bulk nanostructured materials, by engineering very small second-phase particles into a nanometre Al alloy matrix, while further gaining rather than sacrificing its yield strength.
Journal ArticleDOI
Review on superior strength and enhanced ductility of metallic nanomaterials
TL;DR: In this article, the authors present an overview of experimental data and theoretical concepts addressing the unique combination of superior strength and enhanced ductility of metallic nanomaterials, and consider the basic approaches and methods for simultaneously optimizing their strength and ductility, employing principal deformation mechanisms, crystallographic texture, chemical composition as well as second-phase nano-precipitates, carbon nanotubes and graphene.

Principle of equal-channel angular pressing for the processing of ultra-fine grained materials
TL;DR: In this paper, it has been shown that submicrometer-grained structures may be produced in a wide range of materials (e.g. pure metals, metallic alloys including superalloys, intermetallics, semiconductors) by subjecting these materials to a very high plastic strain using either equal-channel angular (ECA) pressing or torsion straining under high pressure.
