It is demonstrated how the complexities of graphite shapes and distributions in cast irons can be described by fractal geometry. A selection of typical graphite morphologies, flake-like and spherulitic, is described unambiguously by two numbers, a shape factor, a, and fractal exponent, D. The meaning of these numbers is discussed and their possible correlations with growth kinetics and mechanical properties are briefly explored.
