Changes in the Morphology of Iron-Containing Phases in Aluminum Alloys
Experimental and thermodynamic studies of multi-component phase diagrams with additions of refining elements have been carried out using Thermo-Calc Software; microstructures of the alloys in as-cast and annealed states have been analyzed. The possibility to obtain iron-containing phases with almost spherical morphology enabling to neutralize negative influence of iron on ductility and fracture strength of alloy has been described.
