Metal Flow at Equal Channel Angular Pressing with Backpressure

摘要

In the present paper a flow pattern of aluminum alloy and copper was investigated by grid procedure, using 2D-modeling and experimental data for ECAP using backpressure. The most important parameters that influence upon flow pattern and deformed state of billets were revealed. We found the most optimal radii of intersecting channels to press the billets, having 16x16 mm in section, from the aluminum alloy and copper in backpressure conditions.
