Abstract
A recently derived equation for nucleation is applied for pure aluminum and Al–6 wt% Cu–3 wt% Si alloy under upward solidification conditions to calculate the surface stress, surface energy, nucleus radius, and Gibbs–Thomson Coefficient as a function of the distance from the chill. The microscopic and macroscopic fields are coupled through a Representative Elementary Volume—REV approach. As expected, higher surface energy and lower critical radius values are observed in positions in which high cooling rates occurred. Then, a nucleation model is carried out to simulate the effect of cooling rates for the molar specific heat capacity of pure Al, Fe, and Nb, and for Al2Cu and Al3Ni2 phases. In the case of Nb, a set of experimental data deviates from high temperatures from theoretical predictions, probably due to high O2 activity as previously observed for the case of pure Fe. A nucleation model for the alloy is proposed as a function of pressure, concentration, and temperature gradients in view to permit the calculation of nucleation radius, surface energy, surface stress, and Gibbs–Thomson Coefficient under non-equilibrium any given cooling rate.
