Resumen:
This study was conducted to investigate the directional solidification of Zn-20%Al and Zn-20%Al-10%Si-3%Cu alloys under different conditions of heat transfer at the metal/mouldinterface. The type of structure obtained in both cases was analyzed and related to thesolidification thermal parameters such as cooling rate, growth rate, thermal gradient andrecalescence which were determined from the temperature versus time curves. These parameterswere correlated with the structure-like length of columnar grains and size of equiaxed grains.The metallographic analyses were done performing quantitative metallography and compositionanalysis of the different alloying elements along the cast samples by SEM (Scanning ElectronMicroscopy) and EDXA (Energy Dispersive X-Ray Analysis). Correlations between properties,structures and thermal parameters were found.
