Interaction of iron-chromium alloys containing 10 and 25 mass% chromium with liquid aluminium. Part I: Dissolution kinetics

The dissolution process of iron-chromium alloys containing 10 and 25 mass% Cr in an aluminium melt at 700°C is found by the rotating-disc technique to be diffusion-controlled and non-selective. Experimentally determined values of the saturation concentration (solubility) and the dissolution rate con...

Summary:The dissolution process of iron-chromium alloys containing 10 and 25 mass% Cr in an aluminium melt at 700°C is found by the rotating-disc technique to be diffusion-controlled and non-selective. Experimentally determined values of the saturation concentration (solubility) and the dissolution rate constant of iron and chromium in liquid aluminium for the Fe—Cr alloys are presented. Evaluated values of the diffusion coefficients of Fe and Cr across the diffusion boundary layer into the melt are also given.
