説明

In order to get the fundamental data about the extrusion method in the coexisting state of liquid and solid in Al-4Cu alloys with magnesium, the influences of extruding pressure, billet temperature and magnesium content on the mechanical properties of the extruded product have been investigated. The tensile strength of the extruded product fluctuates with the billet temperature. As the temperature falls, in other words, as the solid component increases, the tensile strength at first increases and after reaching a maximum, it begins to decrease and thereafter it begins to increase again. The microstructure of the extruded product consists of two different grains. One of them is the same which existed during extrusion and the other one is the grain that appears during cooling.
