Resumen:
A methodology is proposed to obtain the grain growth coefficients
operating during solidification of a near eutectic Al-Ni alloy from data
on solid fraction evolution, latent heat of solidification and., volume
grain density. These parameters are obtained using Newton Thermal
Analysis (NTA), metallographic methods and the Free Growth Method (FG).
In order to validate the methodology a heat transfer-solidification
kinetics model was implemented. Results suggest that this methodology
could be applied to obtain useful information needed to simulate grain
growth during eutectic solidification.
