抄録

It has been found that nodular graphite steel may be more readily obtained in the as-cast condition by addition of a suitable iron-calcium base alloy to molten steel of hypereutectoid composition and of lower silicon content. Steel samples containing 1.1∼1.5%C were melted in a magnesia-lined high-frequency induction furnace. The melt was divided into two or three parts, each part being treated with 0.8 or 2.0% of the iron-calcium base alloy and cast into a CO2 sand mould or a dry sand mould of keel block type. After various heat treatments, test pieces were machined from these steel castings. The result of this experiment may be summarized as follows: (1) The mechanical properties of nodular graphite steel castings in the heat-treated condition were better than those of the as-cast condition. The specimens with spheroidized pearlite structure showed high tensile strength and high ductility such as tensile strength of 70∼85 kg/mm2 and elongation or reduction of area of about 10% respectively. (2) With increasing carbon contents, the ratio of graphitization increased and the specimens with ferrite structures showed stronger graphitization than those with any other structures.
