Abstract

The sludge deposition of JIS die casting alloy ADC12 in the holding furnace was studied. A quaternary intermetallic compound (FeMn)₃Si₂Al₁₅ deposits in the molten metal free from Cr. Critical Fe and Mn concentrations for sludge deposition at a holding temperature T°C are expressed as: %Fe+{3.34-(T-630)/714}%Mn = 2.39+(T-630)/152 A quinary Al-Si-Fe-Mn-Cr compound (FeMnCr) ₃Si₂Al₁₅ deposits in the molten metal containing Cr. Critical concentrations of Mn and Cr in molten ADC12 alloys containing 1.0% of Fe at a temperature T°C are expressed as: %Mn+{4.00+(T-630)/333}%Cr=0.40+(T-630)/500.
