Abstract: “Equal channel angular extrusion (ECAE) is a processing method for introducing an ultrafine grain size into a material. In the present study, a severe plastic deformation process was used to produce ultrafine grained Al with significantly enhanced mechanical properties. This paper reports the mechanical properties and microstructures of the Al specimens processed by ECAE at room temperature.”
