抄録

A blister is one of surface defects for extrusion material of aluminum alloy. In this paper authors investigate about a collapse of billet under extrusion and flow of material in tests using a scale model. From the results, the processing under extrusion can be visualized by using a plasticine and an acrylonitrile pipe. A residual air would be small if a billet length is shorter and a clearance is smaller. Furthermore, it is clarified that the residual air inside the billet causes the blister from rolling into the extrusion material at beginning of extrusion upset. It is considered that the surface defects of the extrusion material can be reduced by solving the above factors.
