Abstract

"FERRO FUNDIDO VERMICULAR DE ALTA USINABILIDADE E ISENTO DE MICROPOROSIDADES". Abrangendo as classes de 350 a 500 MEGA PASCAL de limite de resistência, apresentando uma maior quantidade de grafita por volume de ferro fundido vermicular; sendo este aumento de quantidade de grafita conseguido com nódulos adicionais na microestrutura, de modo que a percentagem desses nódulos também seja aumentada em relação ao volume no ferro fundido vermIcular.
