Evolution of Microstructure Through Various Techniques of Severe Plastic Deformation

Abstract

Severe plastic deformation (SPD) is a structuring technique used to manufacture nanomaterials which are used to shape nanoscale structures. Various techniques of SPD are used for grain refinement which has capability of enhancing mechanical properties of material and its alloys. Various SPD methods like ECAP, HPT, ARB, etc., have their own advantages and disadvantages. Comparison of various techniques has been studied in the current research paper. In all important SPD methods, expert coverage of current achievements and future developments in the industry and research directions including both batch and continuous processes has been provided and a concise introduction to the field of mass production of nanomaterials for nanotechnology using the latest examples from the research. It is suitable for various engineering and industrial applications. It has been concluded that ECAP and HPT are better processes for grain refinement.
