Abstract

''MéTODO APERFEIçOADO PARA OTIMIZAçãO DO REFINAMENTO DE GRãO DE LIGAS DE ALIMìNIO''. Trata-se de um método de controle do refinamento de grãos de certas ligas de alimínio. Os tamanhos de grãos para diferentes valores do índice de crescimento de grãos, GGI, são determinados para o método de fundição usado. O GGI é representado pela soma do valor m(k-1) multiplicado pela concentração de cada elemento na liga de alumínio. Se o valor para uma certa liga for comparado com relações conhecidas entre o valor m(k-1) e o tamanho de grão da composição da liga em estado de fusão, é ajustado para um tamanho de grão ótimo pela adição de um agente que afeta o tamanho de grão. O método pode ser ainda aperfeiçoado pela otimização da quantidade de agente de nucleação.
