| Abstract: | Ultra-fine grained materials produced by equal channel angular pressing(ECAP) have been inten- sively investigated in the past several years.Much improvement has been made in foundemental understanding and practical application of these materials.This article reviews the present state of this field,including the principle of the technigue,deformation behaviour and microstructural evolution during ECAP,structural characterization and mechani cal properties of ECAPed materials. |
