The variations in graphite morphology have been classified; together with the length of the flakes; by standards that have been utilized for many years. K-FGI(KIRIU Flake Graphite Structure Index)of graphitic structure using an image analyses was proposed to estimate the graphite shape and the size of flake graphite cast iron newly here. The obtained supposition graphite area is divided by 100μm of supposition graphite length. The calculated value was defined as TTR(Thick Thin Ratio). Using K- FGI; the influence of the graphite shape on the thermal conductivity; the tensile strength and the hardness of flake graphite cast iron was investigated. The mechanical property and the thermal property were influenced by the graphite morphology and distribution of flake graphite cast iron. © 2016; The WFO (The World Foundry Organization Ltd).
