WebThe graphite is present as tiny balls or spheroids. Because the spheroids interrupt the matrix much less than graphite flakes, nodular cast iron has higher strength and toughness than gray cast iron. The formation of nodules or spheroids occurs when eutectic graphite separates from the molten iron during solidification. WebThe main difficulty in the metallographic preparation of cast iron is to retain the true shape and size of the graphite in its flake, nodular or tempered form. In particular, cast irons with a soft ferritic matrix tend to smear and are prone to deformation and scratching. pecan valley weatherford tx
