Abstract

L'invention concerne un traitement thermique d'alliages comprenant des éléments permettant d'améliorer la résistance des joints de grains. Des composants présentent souvent, juste après le coulage, une faible résistance transversale ou pas de résistance transversale du tout des joints de grains et, par conséquent, des fissures apparaissent et diminuent le taux de production. Le traitement selon l'invention n'engendre pas une faible résistance transversale des joints de grains mais permet de conserver une résistance transversale des joints de grains efficace, de manière que le taux de production de composants sans fissure soit augmenté.
