Abstract

See full text

A method for manufacturing an austempered ductile cast iron and a product made from the austempered ductile cast iron manufactured by the method are disclosed. In the method for manufacturing an austempered ductile cast iron, spheroidizing agent and primary inoculant are added to a raw molten metal to create homogeneous spheroidal graphite creation in a deep part of a matrix and the raw molten metal to which the spheroidizing agent and the primary inoculant are added is injected into a mold to which secondary inoculant is locally applied, to micronize spheroidal graphite of a local structure coated with the secondary inoculant into fine graphite that is easy to machine, thereby enhancing workability as compared with a conventional austempered ductile cast iron.
