Materials strengthened by conventional methods such as strain hardening, solute additions,
precipitation and grain size refinement are often adopted in industrial processes.
But there is limitation to the amount of deformation that these conventional methods can
impact to a material. This study focused on the review of major mechanical properties
of aluminum alloys in the presence of an ultrafine grain size into polycrystalline materials
by subjecting the metal to an intense plastic straining through simple shear without
any corresponding change in the cross-sectional dimensions of the sample. The effect of
the heavy strain rate on the microstructure of aluminum alloys was in refinement of the
coarse grains into ultrafine grain size by introducing a high density of dislocations and
subsequently re-arranging the dislocations to form an array of grain boundaries. Hence,
this investigation is aimed at gathering contributions on the influence of equal channel
angular extrusion toward improving the mechanical properties of the aluminum alloys
through intense plastic strain
