Abstract
Equal channel angular pressing (ECAP) provides an efficient procedure for introducing an ultrafine grain size into a material. In this study, ECAP were conducted on IF-steel to investigate the effect of friction and processing temperatures on the deformation characteristics of the samples. Due to the blocking effect of the previously pressed samples residing in the exit channel, the shear pattern (especially on the bottom region) changes.
