Abstract:

Austempered ductile iron is a perfect constructional material. Its unique properties combining high strength with good elongation follow from the material’s structure, in which a special role is played by a metallic matrix. The growing requirements that cast producers have to meet result in the necessity of developing appropriate tools for the production process control. The present work discusses the state of the art with respect to the modeling of ausferritic ductile iron properties. Furthermore, it puts forward a new approach to the modeling of selected properties which is based on creating logical rules. The proposed approach has been verified with the use of the data set with the data coming from diverse sources and pertaining to more than 1400 melts. The results of the experiment have confirmed the usefulness of the proposed method. In the summary, the method’s further potential development has been considered.
