Abstract

The superior properties of ultrafine-grained materials fabricated by severe plastic deformation (SPD) have attracted the attention of many researchers around the world.  Among the top-ranked countries that are active in this field, Iran is interesting because of the late beginnings of SPD in this country and, subsequently, the highest rate of growth in the number of publications during the last decade. The first Iranian work published in the field of equal-channel angular pressing (ECAP) goes back to 2007, meaning that SPD research covers a period of only about ten years. Nevertheless, since that time there has been an increasing growth rate in the number of Iranian publications dealing with ECAP and especially the introduction of new methods based on ECAP and simulation of the method.  The present overview is designed to summarize the main contributions from Iran in the field of ECAP processing. Interestingly, the main contribution of Iranian researchers in ECAP is focused on simulation/modelling and the introduction of new methods of SPD based on ECAP.
