Abstract

L'invention concerne un procédé de réalisation d'une pièce coulée. Le procédé consiste à refroidir des zones de la pièce coulée devant présenter un grain particulièrement fin par l'intermédiaire de parties minces de la paroi du moule qui ne sont pas encore totalement dissoutes par la masse en fusion, mais qui réalisent une liaison inter-métallique avec la pièce coulée et qui ne peuvent être séparées de la pièce coulée qu'au prix d'une détérioration. Application à la réalisation des pièces coulées.
