Abstract

El tamaño del grano de un producto de metal viable puede mejorarse preestableciendo los dispersoides que suprimen la recristalización durante la fundición. Las regiones externas de un lingote embrionario fundido con enfriamiento directo pueden someterse a recalentamiento antes de que la fundición se termine. A través de la colocación de una rasqueta única y/u otras técnicas de recalentamiento, la temperatura del lingote puede dejarse recalentar (por ejemplo, hasta aproximadamente 410ºC a aproximadamente 420ºC), permitiendo que se formen los dispersoides. La agitación del sumidero del metal fundido puede facilitar la formación de un sumidero más profundo y un tamaño del grano fino deseado en bruto. La formación de los dispersoides durante y/o inmediatamente después de la fundición, puede fijar los límites del grano en el tamaño del grano fino deseado, alentando los mismos tamaños del grano, incluso después de un paso posterior de recristalización y/o de calentamiento para formar una solución sólida homogénea.
