TY - JOUR N2 - A comprehensive understanding of melt quality is of paramount importance for the control and prediction of actual casting characteristics. Among many phenomenon that occur during the solidification of castings, there are four that control structure and consequently mechanical properties: chemical composition, liquid metal treatment, cooling rate and temperature gradient. The cooling rate and alloy composition are most important among them. This paper investigates the effect of the major alloying elements (silicon and copper) of AlSi-Cu alloys on the size of secondary dendrite arm spacing. It has been shown that both alloying elements have reasonable influence on the refinement of this solidification parameter L1 - http://journals.pan.pl/Content/86205/PDF/04_paper.pdf L2 - http://journals.pan.pl/Content/86205 PY - 2012 IS - No 1 DO - 10.2478/v10266-012-0004-2 KW - Secondary dendrite arm spacing KW - AlSiCu alloy KW - Aluminium casting KW - solidification A1 - Djurdjevič, M.
