Abstract  The die geometry has a massive effect on the plastic deformation behavior during pressing of material processed by equal channel angular pressing (ECAP) method; subsequently the properties of the processed material are strongly dependent on it. Two categories of designed and manufactured dies are used for equal channel angular pressing, a 120 0 sharp angle and a 90 0 round –cornered (20 0) dies, that produce strain per pass through both dies of ~0.7 and ~1.05   respectively. The microhardness developed in Al-Si alloy during ECAP using route B C. The microhardness increased by a factor of >1.5, after only 1 pressing. Subsequently, the hardness increases slightly up to 8 pressings through the 120 0 sharp angle die, while it is increased by a factor of ~2.6 after 5 passes by using the 90 0 round cornered die, comparing with that for the cast workpiece.
