Summary

In the recent years considerable efforts have made in order to produce ultrafine grained materials by imposing large plastic straining by many different techniques such as equal-channel angular pressing (ECAP) [1–4], severe plastic torsion straining (SPTS) [1, 5–7] or accumulative roll bonding (ARB) [8–10]. However, ECAP and SPTS seem to be of little use when manufacturing plate-shaped materials efficiently and only ARB is appropriate for producing SPD plates or sheets. Efforts, therefore, have been focused not only on analysing the properties of the materials subjected to severe plastic deformation (SPD) but also on the design and development of new techniques that could compete with the processes cited before. One of the most recent contributions from that point of view is the constrained groove pressing (CGP) developed by Shin et al. in 2002 [11].
