Abstract. The paper reports on an investigation into the various aspects of an axisymmetric sintered compound flow behaviours of powder preforms which have been compacted and sintered from atomized metal powder. Many forging processes involve flow of preform in more than one direction. For the purpose of die and process design it is often necessary to determine the flow behavior and the forging force. Analysis of a general axisymmetric problem is discussed and presented graphically. In addition the fundamental interest that it emphasizes the power of upper-bound when applied to the prediction of compound sintered metal flow.
