| Abstract Scope |
In recent years, an aluminum double skin panel, which has a complicated and wide cross- sectional shape and is manufactured by extrusion is used for railway vehicles. It is difficult to manufacture a double skin panel exceeding 600 mm width in the current forward extrusion process. However, from the viewpoint of weight saving, there is a demand to make double skin panel with larger width. So it is proposed to manufacture double skin panel with complex extrusion of multi billets. Complex extrusion of multi billets is suitable for producing complicated and wide extruded shape. And the joint part of the double skin panel is joined in a plate shape. In this study, industrial pure aluminum A1050 and representative extruded aluminum alloy A6063 were extruded into a plate shape, and the joining state was evaluated by tensile test, micro Vickers hardness test, microscopic observation and numerical analysis. |
