Abstract (english)
Due to European Union legislative and recently the difficulties faced by casting manufacturers, more and more attention is focused on raw materials. Raw materials are found at the beginning of all industrial value chains. These critical (CRMs) and strategic raw materials (SRMs) are often indispensable inputs for a wide set of strategic sectors including renewable energy, the digital industry, the space and defence sectors, health sector all connected to the metal industry. Aluminium and its alloys plays an important CRMs and SRMs. Standard aluminium alloy AlSi9Cu3(Fe) (EN AC 46000) is widely used in the automotive and transport industry. High mechanical properties such as strength and hardness, as well as elongation and corrosion resistance are the main advantages of AlSi9Cu3(Fe) alloy. The functional and useful properties of aluminium cast alloys are dependent from the chemical composition, melt treatment, solidification rate, casting process and potential heat treatment. Most of them are conditioned by the microstructural development. This paper investigates the recycling potential of AlSi9Cu3(Fe) alloy using completely return material without any additions or refining. The presence of wide range of alloying elements AlSi9Cu3(Fe) alloys indicates development α-Al15Si2M4 (M= Cr, Fe, Mn, Mo), β-Al5FeSi, Al2Cu and even more complex one such as Al3Cu2Mg9Si7 using theoretical modelling. Complex solidification path indicates primary aluminium αAl, eutectic phase αAl+βSi, intermetallic phase on the iron base in Al5FeSi and “Chinese script” morphology, intermetallic phase on the magnesium and copper base such as Mg2Si and Al2Cu, and complex intermetallic such as Al8Mg3FeSi2 and Al5Mg8Si2Cu2 phases. Thermodynamic effects of elements interaction during solidification sequence significantly influence on solidification path and manner. Although the investigated samples maintain high tensile strength and elongation, slight degradation in chemical composition and therefore in thermodynamic effect, significantly influence on microstructure development. In despite of chemical composition degeneration, obtained microstructure was correct and therefore justified achieved high mechanical properties. Therefore, on the base of thermodynamic and microstructural investigation of the secondary AlSi9Cu3(Fe) alloy indicated raw material as a quality charge material with good application and recycling potential.
