ABSTRACT --- Isothermal extrusion of aluminum alloys is a method of maintaining
a constant temperature of an extruded section in the bearing zone of the die in order
to obtain a high steady quality of dimensions and mechanical properties. In this study,
an equation for calculating the initial billet temperature that performs isothermal
extrusion is proposed and confirmed. The concept of the equation for isothermal
extrusion is to assign an adequate initial billet temperature, container temperature and
ram speed to equalize the heat flow from the billet to the container and the heat
generation by the shearing deformation of metal close to the container wall. Under the
consideration of the parameters in the heat generation in the FEM analysis, adequate
extrusion conditions are obtained. Using the results of FEM analysis, isothermal
extrusion has been realized in the extrusion of aluminum alloy 6063.
