Abstract

"FUNDIçõES DE FERRO COM GRAFITE COMPACTADO OU ESFEROIDAL PRODUZIDO DETERMINANDO COEFICIENTES A PARTIR DE CURVAS DE RESFRIAMENTO E AJUSTANDO O CONTEúDO DE AGENTES MODIFICADORES DE ESTRUTURA NA CORRIDA" A microestrutura na qual uma certa corrida de ferro fundido solidificará pode ser prevista com alta precisão realizando quatro cálculos independentes e então escolhendo o cálculo que dá o melhor resultado. Os cálculos são de preferência realizados por um computador.
