Abstract	Material processed through severe plastic deformation (SPD) achieved ultra large plastic strain with improved mechanical properties at minimum cost as compared to other methods. Among all SPD method, equal channel angular pressing (ECAP) produces defect-free ultra large plastic strain without changing initial dimension of the sample, when pressed through two intersecting channels. In the present work, a hybrid SPD process (ECAP-based extrusion) is used for plastic deformation of Al1070 alloy billet, and the results (equivalent stress, effective plastic strain and punch load) are compared with conventional ECAP-based technique. The effect of corner radius (outer radius, inner radius) and extrusion die angle on the deformation behaviour i.e. effective plastic strain, equivalent stress and load at die wall has been studied using finite element method. It is observed that extrusion die angle has negligible influence on equivalent stress, whereas equivalent stress decreases with increase in outer radius. Effect of coefficient of friction is also noticed on the flow behaviour of billet.
