Numerous analytical and numerical studies on equal channel angular pressing have been performed in recent years. The present work focuses on the effects of friction, initial material properties and die geometry and aims at enhancing the understanding of these effects on strain homogeneity and mean e
## Abstract The 3D grain boundary character distribution (GBCD) of a sample subjected to equal channel angular pressing (ECAP) after eight passes and successive annealing at 650βΒ°C for about 10βmin is analyzed. The experiments are conducted using a dual beam system, which is a combination of a focu
