Examination and Simulation of Silicon Macrosegregation in A356 Wheel Casting

A modified Cellular Automaton model was presented to simulate the evolution of dendritic microstructure in low pressure die casting of Al-Si Alloy, which accounted for the heterogeneous nucleation, the solute redistribution both in liquid and solid, the interface curvature and the growth anisotropy during solidification. The free growth of single equiaxed dendrite and the evolution of multi dendrites with various crystallographic orientations were predicted. The variation of the dendrite tip velocity and local solute concentration at the solid/liquid interface were analyzed. The grain morphology of aircraft turbine wheel casting at different specimen points were predicted and compared with experimental results.

Wheel Casting

Recent interest in the literature on ternary compounds of the AlCuFe type has been prompted by the discovery of stable quasicrystalline phases in these type of alloys (1) . Therefore, different investigationes have been carried out in the past, related with the structural characteristics and also the mechanical properties of these compounds (2) . It is interesting to point out that very few studies have been carried out on the structural characteristics of the phases which commonly coexist with the icosahedral phase in this ternary alloy (3) . In this investigation an assessment of the chemical and structural properties of the phases obtained in alloys of AlCuFe is carried out.Ternary alloys with approximately 20 different compositions have been prepared. The compositional ranges were: Al(60-65%at), Cu(20-25%at) and Fe(10-15%at). The preparation of the alloys used two different casting process; a gravity chill casting technique and also the spin wheel casting method. These casting techniques were able to provide different cooling velocities in the final ingots or metallic strips.
