Abstract As a promising severe plastic deformation (SPD) technique, equal channel angular pressing (ECAP) imposes large shear strain into materials without changing the cross-section shape. Despite of considerable investigations concentrating on grain refinement effect of ECAP, this new emerging technique has been increasingly applied in other fields, and significant progresses have been achieved.This review outlines the working principle of ECAP, summarizes the state of art of metal powder consolidation and chip recycling through ECAP process, makes a vivid description over the corresponding research highlights and different modification strategies of domestic and international researchers, and ends in a limitation-based development prospect in this field.
