..., at higher cooling rates, the system behaves as though the eutectic point is shifted to higher silicon contents, and the eutectic temperature is depressed. Figure 2 illustrates the effect of this apparent shift in the eutectic point on the microstructure of a typical aluminum-silicon alloy. Figure 2...

... Abstract Cast iron exhibits a considerable amount of eutectic in the solid state. This article discusses the structure of liquid iron-carbon alloys to understand the mechanism of the solidification of cast iron. It illustrates the nucleation of the austenite-flake graphite eutectic, austenite...
