Abstract

Plastic deformation of metals or alloys in the forming processes is often called metal flow. Metal flow in hot extrusion of an aluminum alloy is closely connected with distortion of the cross section of the product and with peripheral recrystallization which causes streaks after anodizing. Then, the metal flow characteristics and the strain conditions in the deformation zone in hot extrusion of 6063 Aluminum alloy were investigated by employing the visioplasticity method. Furthermore, metal flow control technique by generating some temperature difference, in which deformation resistance of the billet becomes lower at higher temperature, in the deformation zone in the billet could be confirmed in the present investigation. Temperature difference could be generated by using the extrusion die constructed with multiple die materials having different thermal conductivities.
