초록
It has been studied that the aluminum extrusion with the ingot-recycled composite billet that is casted. The billet is composed of the inner rod with the recycled and the outer ring with the ingot aluminum. For easy producing the tensile specimens to evaluate the bonding strength between recycled and ingot material, the extrusion die was designed. Two types of the billet are extruded. One is a composite billet that is casted. The other is an assembled billet with the turned bars. The strength is measured from tensile tests with extruded specimens. The effect on the strength of the oxidized layer between the materials has been researched with EDS analysis.
