  • ABSTRACT: An object of this study is the effect of the carbide phase quantity and austempering temperature on the mechanical properties of samples made of carbidic austempered ductile iron (CADI). Analysis of variance and regression analysis have been carried out on the basis of experimental data obtained. On the basis of regression models obtained, three multi- objective optimization tasks have been set out solved. Thus, the optimal values of liquid carbide phase and austempering temperature of CADI have been established.
