Abstract (en)
The described process contemplates formation of an aluminium casting (1a) by high-pressure or gravity die-casting. Casting (1a) drawn out of the casting mould, is heated and submitted to compacting by being closed into a forging die geometrically similar to, but of smaller sizes than the workpiece itself. Elimination of any porosities in the material, and also crushing of dendritic crystalline aggregates and elongation of the aluminium crystals in the form of fibres parallel to the finished-casting (1) surfaces, is achieved. <IMAGE>
