Abstract

In this study, the equal channel angular pressing (ECAP) process was performed on the engineering magienium alloy (AZ31) with different Back Press (BP). The effect of BP on the strain condition and flow paths may differ as the statically deformed portion of the sample passes through the strain zone. Quantitative evaluation of the flow model is performed from the flownet of DEFORM tools for magienium alloy (AZ31). The BP application of 25, 50 and 100 MPa results in the forward rotation of typical shear structural coponents in the transverse direction.  The complex (20 x 20 x 200) mm ECAP engine is used with movable outer walls and specially designed sliding bottoms for low friction (moving die). The flow model is made by a cubic flownet of the Deform tool on the workpiece. Structural features and initial micro- hardness measurements made on the X and Y planes of the workpiece also received a special attention. Since BP leads to increased density leading to the improved in micro-hardness can be attributed to the change in texture.
