Opis:: This article deals with the fatigue properties of newly used AlZn10Si8Mg aluminium alloy where the main aim was to determine the fatigue strength and compare it with the fatigue strength of AlSi7Mg0.3 secondary aluminium alloys which is used in the automotive industry for cyclically loaded components. AlZn10Si8Mg aluminium alloy, also called UNIFONT 90, is self-hardening (without heat treatments), which contributes to economic efficiency. This is one of the main reasons why is compared, and may be an alternative replacement for AlSi7Mg0.3 alloy which is heat treated to achieve required mechanical properties. The experiment results show that the fatigue properties of AlZn10Si8Mg alloy are comparable, if not better, than AlSi7Mg0.3 alloy. Fatigue properties of AlZn10Si8Mg alloy are achieved after seven days of natural ageing, immediately after casting and achieving value of fatigue strength is caused by structural components formed during solidification of the melt.

Opis:: The porosity formation in secondary aluminium cast alloys are one of the main aspect which can affect the final properties of casts. Whereas these materials are especially used for production the automotive casts such as engine blocks, cylinder head, chassis components and so on, it is need the production of the casts without deleterious defects. The contributions deals with comparison of the porosity formation in secondary AlSi9Cu3 cast alloy when different moulds (the metallic mould and sand mould) for casting were used. The material was gravity casted in the both mould. The differences in microstructure and porosity formation were studied by using light metallography microscopy and image analyser software. The evolution shows that the experimental material casted into the metallic mould had about 98.78% smaller porosity size in comparison to the material casted into the sand mould, therefore it showed better properties.

Opis:: Nowadays, a transportation industry creates a lot of metal scrap because production and use of cars are on the increase worldwide. This is based on the fact that increase in the production of cars increases usage of aluminium alloys in transportation applications. Therefore, it is necessary to reduce the production of components from primary aluminium alloy and increase their replacement with secondary-recycled-aluminium alloys because the production of recycled aluminium alloys is less expensive and less energy-intensive than the creation of new aluminium alloy through the electrolysis. In addition, the recycled aluminium alloys have comparable microstructural parameters and properties as the same primary aluminium alloys.
Dank weltweiter Produktionserhöhung und Benutzung der Fahrzeuge produziert die Verkehrsindustrie heute viel Metallabfall. Wie steigert die Fahrzeugerzeugung, so steigert auch die Benutzung von Aluminiumlegierungen. Es ist nötig, die Produktion von Aluminiumprodukten aus Primäraluminium zu reduzieren. Die Produkte müssen also durch die Produkte aus Sekundäraluminium eingesetzt werden. Während die Schmelzflusselektrolyse bei der Gewinnung von Aluminium aus Bauxit 100 Prozent Energie verbraucht, sind es beim Recycling etwa vier bis sechs Prozent. Das Aluminium-Recycling leistet deshalb einen beträchtlichen Beitrag zur Einsparung von Energie, und dient damit gleichzeitig auch dem Umweltschutz. Noch dazu, die Legierungen vom Sekundäraluminium haben vergleichbare Eigenschaften wie dieselben Legierungen von Primäraluminium.

Opis:: This paperwork is focused on the quality of AlSi6Cu4 casting with different wall thicknesses cast into the metal mold. Investigated are structural changes (the morphology, size, and distribution of structural components). The quantitative analysis is used to numerically evaluate the size and area fraction of structural parameters (α-phase, eutectic Si, intermetallic phases) between delivered experimental material and cast with different wall thicknesses. Additionally, the Brinell hardness is performed to obtain the mechanical property benefits of the thin-walled alloys. This research leads to the conclusion, that the AlSi6Cu4 alloy from metal mold has finer structural components, especially in small wall thicknesses, and thus has better mechanical properties (Brinell hardness). These secondary Al-castings have a high potential for use in the automotive industry, due to the thin thicknesses and thus lightweight of the construction.
