When is a Cast Iron Eutectic?

The literature often mentions that cast irons appear eutectic by thermal analysis are hypereutectic if one refers to the equilibrium phase diagram. This is a source of ambiguity and confusion. experimental results on has previously shown taking into account solidification path during primary precipitation graphite makes it possible differentiate slightly from very irons. approach applied here iron which appears when inoculated hypoeutectic not. Thus, confirmed growth only becomes effective minimal undercooling reached, independently inoculation. However, an alloy with carbon equivalent at boundary between mildly strongly alloys can analysis.
