Abstract: A device for the plastic forming of a workpiece made of metal or a metal alloy by ECAP is described. The device comprises more than two channels, wherein an inlet channel and an outlet channel are provided, wherein these channels indirectly connect to one another and are arranged approximately perpendicularly to one another. Furthermore, a method for the plastic forming of a workpiece made of metal or a metal alloy ECAP is described. The workpiece is pressed once or multiple limes through a device having more than two channels, wherein the workpiece is plastically formed by a single or multiple pressing through an inlet channel and an outlet channel which indirectly connects to the inlet channel and is arranged approximately perpendicularly thereto.
