The alstruc microstructure solidification model for industrial aluminum alloys

  • Published:
Metallurgical and Materials Transactions A Aims and scope Submit manuscript

Abstract

The model predicts the solidification path in the aluminum corner of the AlCuFeMgMnSi phase diagram, with compensation for solid-state diffusion and particle growth undercoolings. Input is the composition and the rate of cooling. Output is the temperature vs fraction solid; the solid-state concentration profiles; the type, volume fraction, and size of the intermetallic particles; and also the temperature-dependent thermal conductivity, density, specific heat, and heat of fusion for use in thermal models.
