Professor Marcello Cabibbo was born in Palermo in 1971 and graduated in Physics at the Alma Mater Studiorum University of Bologna in 1996. He took his PhD degree in Materials Engineering at the University of Tor Vergata in Rome (2000). He was a university researcher from 2000 to 2007, and from that year, he has been an associate professor of Metallurgy with the DIISM/Università Politecnica delle Marche. In his early years of academic career, he won several awards, of which the most relevant are Young Researcher award from Univer - sità Politecnica delle Marche (2000 and 2002) and Researcher of the Year award from Università Politecnica delle Marche (2003) and he was third at a national ranking for the Materials Science Microscopy SISM (Italian Society of Microscopy Sciences) (2004). He is currently a member of the European Microscopy Society (EMS), the Italian Society of the Microscopy Sciences (SISM), and the Italian Metallurgy Association (AIM). He is the co - author of more than 170 journal papers, two-third of which published in peer-reviewed (ISI) international journals, and most of them as corresponding author (113 according to Scopus, ISI.

Grain size is recognized as a key microstructural factor affecting mechanical and, to some extent, physical properties of metals and metallic materials. For this reason, all the means designed to control and modify the grain size are considered a proper way to design and tailor metallic materials with desired properties. In this sense, microstructure refinement through severe plastic deformation (SPD) techniques can be considered a key method for this purpose. A typical SPD process is currently defined as any method of metal forming under extensive hydrostatic pressure intended to impose a very high strain on a bulk solid without involving any significant change in the overall dimensions and having the ability to produce exceptional grain refinement. What makes SPD processing techniques so popular and attractive is the possibility of using them to enhance the strength behavior of conventional metallic materials by a factor of up to eight for pure metals such as copper and by some 30-50% for alloys. Despite the impressive property improvement achievable with SPD techniques, their uptake by industry has been rather sluggish. This book intends to give a panorama of the typical SPD techniques intended to optimize the mechanical and physical properties of metals through a significant grain size reduction process. Modeling for this purpose is also presented.
