Chapter 3 - Severe Plastic Deformation Methods for Sheets

Abstract

This chapter aims to clarify the functional and structural principles of ultrafine grained and nanostructured sheet production processes developed over the past two decades. As mentioned in the previous chapters, severe plastic deformation (SPD) methods are used to produce bulk material, sheets, and tubes. In this chapter, we will only refer to the methods that are suitable for sheet forming. Furthermore, we will consider the features of each procedure in detail. The techniques introduced in this chapter are all top-down approaches in which materials with ultrafine or nanostructured grains are produced from coarse-grained materials by severe plastic deformation.
