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.
In recent years, magnesium alloys have gained widespread popularity as construction materials. This is due to their low density, high strength properties, and advances in their production technology. Properties of magnesium alloys depend primarily on the type, quantity, and quality of elements present in their composition. It is therefore necessary to carry out research on the further optimisation of the production technology of these alloys. This article presents the results of studies carried out in order to determine the type, form, and parameters of the process of introducing selected alloying elements to magnesium in a manner which enables the manufacture of alloys with predetermined chemical composition. As part of the work, elements such as Al, Zn, Mn, Zr, Si, Cu, Ca, as well as rare earth elements (RE) were introduced into the liquid magnesium. The alloying elements were introduced into the melt at different temperatures in either a metallic form or as master alloys. While conducting studies, respective solubility graphs were plotted for the alloying elements showing the time taken for each element to dissolve to the required form at a specific temperature and concentration. The studies resulted in the development of several techniques of introducing selected alloying elements, which enabled the manufacture of various types of alloys. Keywords: magnesium, magnesium alloys, alloying elements, magnesium castings Streszczenie W ostatnich latach stopy magnezu cieszą się coraz większym zainteresowaniem jako materiały konstrukcyjne. Związane jest to z ich niską gęstością, dobrymi własnościami wytrzymałościowymi oraz postępem w technologii ich wytwarzania. Własności stopów magnezu zależą głównie od rodzaju, ilości i jakości pierwiastków wchodzących w ich skład. Konieczne zatem jest prowadzenie Dawid Kapinos M.Sc., Bogusław Augustyn M.Sc., Marcin Szymanek M.Sc.: Institute of Non-Ferrous Metals in Gliwice, Light Metals Division in Skawina, Skawina, Poland; e-mail: dkapinos@imn.skawina.pl 142 badań nad optymalizacją technologii otrzymywania stopów na osnowie magnezu.W artykule przedstawiono wyniki badań mających na celu określenie sposobu, postaci i parametrów wprowadzania wybranych dodatków stopowych do magnezu tak, aby możliwe było otrzymanie stopów o założonym składzie chemicznym. W ramach pracy do ciekłego magnezu wprowadzano pierwiastki stopowe, takie jak: Al, Zn, Mn, Zr, Si, Cu, Ca oraz pierwiastki ziem rzadkich (RE). Skład-niki stopowe wprowadzano do ciekłego magnezu w postaci metalicznej oraz zapraw w różnych temperaturach. Podczas realizacji badań wyznaczono wykresy rozpuszczalności dodatków stopowych przedstawiające czas potrzebny na rozpuszczenie pierwiastka w danej postaci, przy określonej temperaturze i koncentracji. Przeprowadzone badania umożliwiły opracowanie technologii wprowadzania wybranych dodatków stopowych, dzięki czemu możliwe jest wytwarzanie różnych gatunków stopów.
