โฆ Synopsis
AbstractConsiderable evidence exists in the literature on graphite to indicate that it produces curved crystals bounded by basal planes but formed by growth in the basal plane. This evidence is supplemented by recent observations on pure Fe-C-Si alloys which show that graphite in cast irons can also undergo curved crystal growth. A model of graphite spherulite growth in cast iron is presented. The model is based upon curved growth of graphite during solidification. and indicates that spherulitic growth is circumferential rather than radial.
