Abstract (english)
The most common aluminum alloy in automotive industry is the AlSi9Cu3(Fe) alloy due to relatively high mechanical properties, fluidity and resistance to hot cracking. The mechanical properties of aluminium cast alloys are strongly dependent from the microstructure developed on the base of chemical composition and casting process with the emphasis on solidification sequence. Green production is an imperative in nowadays industry. Usage of secondary charge material comprehend to the green production certification with 0% CO2 footprint when own return has been used. Maintaining the alloy quality with regard to functional properties while promoting green production makes economical production imperative. In this research, modeling of the solidification sequence in equilibrium and non-equilibrium conditions was carried out and compared with the obtained microstructure for a conventional AlSi9Cu3(Fe) alloy and alloy made of 100% return charge material. Modelled equilibrium phase diagram enables solidification sequence prediction which can be easily confirmed using metallographic analysis. Modeling of solidification sequence revealed some differences in solidification path. Microstructural investigation of obtained samples confirms the presence of following phases: primary aluminium evolution (αAl), iron phases (Al5FeSi, Alx(Fe,Mn)yCuuSiw), primary eutectic phase (αAl+βSi) as well as other intermetallic phases as Al7Cu2Mg, Al5Mg8Si6Cu2, Al2Cu and Al8Mg5FeSi2. The comparison of the obtained results indicates a lowering of the main alloying element Si and thus an influence on the displacement of the solidification sequence equilibrium. Despite the observed differences in the solidification path, the comparison of the microstructures for both cases (conventional and 100% return alloy) does not reveal a degradation in the quality of the alloy. The quality assessment thus indicates that production with 100% recycled AlSi9Cu3(Fe) charge material meets all functional properties in the automotive industry.
