WebCast iron material groups include white and grey cast irons (Fig. 13.10A). ... Abnormal graphite flake forms shows an abnormal flake morphology known as sooty or spiky graphite. It occurs in irons containing Pb and H; Pb may be introduced from contaminated scrap. Austenitic irons can dissolve more Pb than unalloyed irons and display more ... Webmicrostructure of cast iron is through the control of cooling rates during solidification. To control cooling rate, the heat storage capacity of the mould is important. This paper presents the report of a study on the characteristic effects of graphite flake sizes on some mechanical properties of grey cast iron.
