Mm. Haque et Jm. Young, PRODUCTION OF SPHEROIDAL GRAPHITE ALUMINUM CAST-IRON AND THE FACTORS AFFECTING IT, Journal of materials processing technology, 55(3-4), 1995, pp. 186-192
An investigation has been carried out into the production of spheroida
l graphite aluminium cast iron, which was found to be affected by the
melting technique and the inoculation treatments. These vital factors
were evaluated in this study, thereby establishing a unique melting pr
ocedure together with an inoculation technique. As a result, it is pos
sible to obtain a carbide-free pearlitic matrix including a high nodul
e count with a greater degree of nodularity. The results also show tha
t the solidification characteristics of the Fe-C-Al alloy system are m
ore complicated than those of the silicon-bearing system. Therefore, s
pecial attention is necessary to produce spheroidal graphite aluminium
cast iron.
