Abstract

ECAE is defined as metal forming processes in which a very large plastic strain is imposed on a bulk process in order to make an ultra-fine grained metal. In this research, the PLASTIC DEFORMATION BEHAVIOR and the grain size of polycrystalline aluminum, in ECAE process, is predicted by using the BEZIER METHOD and the UPPER BOUND THEORY. Also, the effects of inner corner radius, the die angle and the angle of outer curved corner on strain, strain rate and grain size is studied and then is simulated. It is found that deformation rate decreases with increasing the die angle, the outer curved corner angle and the inner corner radius A good agreement is found between the SIMULATION results with various experimental data.
