Abstract
Batch severe plastic deformation (SPD) processes are mainly used for laboratory
purposes. More industrially oriented are continuous processes among which the new SPD process
of Incremental Equal Channel Angular Pressing (I-ECAP) is an attractive option. This paper
investigates the feasibility of using I-ECAP for nanostructuring of plates rather than bars. First, a
3D finite element simulation has been performed which shows the importance of restricting
material flow in the direction of plate width. A laboratory rig has been designed, which converts the
vertical movement of the machine crosshead into an oblique movement of the reciprocating punch.
Preliminary trials of I-ECAP have been carried out on a 4x30x100mm Al 1070 plate. Metallurgical
samples after 4 and 8 passes of I-ECAP (route A) have been investigated using TEM. In conclusion,
the new SPD process of I-ECAP is capable of processing plates, which opens up new possibilities
of nanostructuring metals on an industrial scale.
