Study of Interface of an A1 Wire Inserted in Gray Cast Iron

Lost foam casting has the capability of putting different types of fibers inside the polystyrene pattern before casting process which leads to production of composite. Furthermore, the process utilized in this research can be regarded as a promising approach for in mold alloying, and study of interfacial reactions between a given melt and supposed solid insert. In this study, Al wire was put inside the polystyrene pattern and then gray cast iron poured. The results show interesting effects of Al in cast iron. Microstructure and effect of Al in formation of different phases were studied by SEM and optical microscopes. Results show that Al affected graphite in gray iron. Graphite with small size and spherical shape formed. In addition, formation of different components from Fe-Al observed.
