Kinetic Study of Intermetallic Formation on Die Material in Aluminum Molten Alloy Containing Various Additional Elements

Abstract:

The formation behavior of intermetallic layers on die material immersed in aluminum molten metal was investigated by using dipping test facility. And the metallurgical parameters affecting on the kinetics of intermetallic formation were discussed as functions of additional elements such as Fe, Mn and Cr in order to propose a practical guideline for control of molten metal in manufacturing processes. It was found that the intermetallic layers consist of α-AlFeSi, β-AlFeSi and θ-AlFe. The kinetic of intermetallic formation was highly dependent on not only the gradient of iron content through the interface between die material and molten alloy but also the relative formation temperature of primary intermetallic phase.
