Abstract

L’invention a pour objet des alliages inoculants destinés au traitement de la fonte de moulage contenant (en poids) de 0,005% à 3% d’un élément du groupe bismuth, plomb et antimoine, de 0,3 à 10% de métaux de groupe des terres rares et éventuellement de l’aluminium jusqu’à 5% et du calcium jusqu’à 0,5%, le reste étant du ferro-silicium, le lanthane constituant plus de 90% des métaux des terres rares entrant dans sa composition. Les alliages selon l’invention permettent une inoculation efficace de la fonte et évitent l’apparition de micro-retassus dans les pièces moulées. Les alliages sont conditionnés sous forme depions soit en poudre.
