Evolution of Mechanical and Microstructural Properties of ECAP Deformed Copper
Summary
Over the last few years [1], equal channel angular pressing (ECAP) has become a popular method for producing bulk ultra-fine structured materials. It allows repetitive pressing of a billet through a die having two intersecting channels without changing the billet's cross-sectional dimensions. Therefore, very high shear strains can be introduced into the workpiece [2,3].
