“…The product of melt spinning is a thin ribbon, which in the case of alloys cast is characterised by a width comprised in the range of 1400-3500 µm and a thickness of 50-150 µm. In this form it is an intermediate product for further processing steps such as fragmentation, cold compaction, consolidation and hot extrusion yielding the solid components or, eventually, parts shaped by die forging [7,8,[10][11][12]. To improve its strength properties, the alloy is heat treated, e.g.…”

“…Due to the specific conditions, the method of Rapid Solidification allows the manufacture of materials with ultrafine grain structure, using alloys of standard and non-standard chemical composition. Rapid Solidification has also another advantage, and it is the possibility to make materials with properties unattainable by conventional processes [11][12][13][14].…”

In the aluminium alloy family, Al-Zn materials with non-standard chemical composition containing Mg and Cu are a new group of alloys, mainly owing to their high strength properties. Proper choice of alloying elements, and of the method of molten metal treatment and casting enable further shaping of the properties. One of the modern methods to produce materials with submicron structure is a method of Rapid Solidification. The ribbon cast in a melt spinning device is an intermediate product for further plastic working. Using the technique of Rapid Solidification it is not possible to directly produce a solid structural material of the required shape and length. Therefore, the ribbon of an ultrafine grain or nanometric structure must be subjected to the operations of fragmentation, compaction, consolidation and hot extrusion. In this article the authors focussed their attention on the technological aspect of the above mentioned process and described successive stages of the fabrication of an AlZn9Mg2.5Cu1.8 alloy of ultrafine grain structure designated for further plastic working, which enables making extruded rods or elements shaped by the die forging technology. Studies described in the article were performed under variable parameters determined experimentally in the course of the alloy manufacturing process, including casting by RS and subsequent fragmentation.
