Abstract

"AGENTE DE REFINO DE GRãO PARA PRODUTOS DE ALUMìNIO FUNDIDOS". A presente invenção refere-se a um agente de refino de grãos para produtos de alumínio fundido contendo titânio, compreendendo partículas formadas de uma matriz de um material dúctil, no qual estão uniformemente dispersas partículas de boro tendo um tamanho médio de partícula de 0,1 a 10 <109>m. Quando os produtos de alumínio fundido não contêm titânio, o material dúctil compreende titânio. O agente de refino de grão conforme a invenção não necessita ser formado em uma liga principal antes de ser adicionado ao alumínio fundido para ser lingotado.
