摘要
The interaction parameter between Cu and Al in molten iron containing high levels of Al was measured using a chemical equilibrium technique. A molten Fe Al alloy was equilibrated with a molten Ag-Cu alloy in an Al2O3 crucible at 1 823 K. The activity coefficient of Cu in Fe Al alloys was measured to be -2.33 while varying the concentration of Al in a range from 0.04-0.2 mol%. The influence of Cu on the deoxidation equilibrium of Al and O was estimated using the above interaction parameter. The results indicate that under a constant Al concentration, a contamination of several percent of Cu raises the O concentration in high Al steel.
