초록
Aluminum alloys are not only lightweight materials, but also have excellent thermal conductivity,enhance the densification behavior of metal powders of aluminum. Investigation on the extrusion processing com-bined with equal channel angular pressing for densification of aluminum powders was performed in order todevelop a continuous production process. The continuous processing achieved high effective strain and full rel-ative density at 200℃. Optimum processing conditions were suggested for good mechanical properties. Theresults of this simulation helped to understand the distribution of relative density and effective strain.
