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.
