Effect of One Step In-Mould Inoculation Method on the Characterization of Thin Wall Ductile Iron

Abstract

Unlike gray iron whose production tends to stagnate, ductile iron enjoy growth exceeding 3% per year [1]. In the recent years basically interest on minimizing the weight of casting components and increasing the mechanical properties. This motivates automobile manufacturers to decrease the weight of automobile leads in the 1970's by reducing the thickness of steel sheets [2-4]. Inoculation which is a means controlling the structure and properties of cast irons by increasing the number of nucleation sites available for the growth of graphite nodules is an
