Descripción
Directional solidification experiments were conducted in a succinonitrile–0.24 wt% camphor alloy with an emphasis on the planar front interface temperature dynamics using different sample thicknesses. The interface temperature was found to depend significantly on the thickness due to non-negligible convection effects in the thicker samples. The results were interpreted with the help of an order of magnitude analysis and a boundary layer model, which permitted estimation of the solute macrosegregation profile. The experiments and corresponding analyses performed in this work constitute an experimental characterization of convection effects as a function of sample thickness.
Des expériences de solidification dirigée ont été menées dans un alliage succinonitrile–0,24% en poids de camphre en se concentrant sur la dynamique de la température de l’interface du front plan en utilisant différentes épaisseurs d’échantillons. La température d’interface s’est avérée dépendre de manière significative de l’épaisseur en raison d’effets de convection non négligeables dans les échantillons plus épais. Les résultats ont été interprétés à l’aide d’une analyse d’ordre de grandeur et d’un modèle de couche limite, qui ont permis d’estimer le profil de macroségrégation du soluté. Les expériences et les analyses correspondantes réalisées dans ce travail constituent une caractérisation expérimentale des effets de convection en fonction de l’épaisseur de l’échantillon.
