Abstract

See full text

The present invention relates to improvements of equal channel angular extrusion (ECAE). It provides a preservation of billet shape, a simple billet ejection from tool, application of backpressure and minimizes or eliminates flashes and cracks during multi-pass processing. That way, ECAE can be performed at a large scale as a productive and cost effective industrial operation without billet reshaping and preheating between passes.
