• When Cu-Mg alloy is added to molten iron, a part of magnesium in Cu-Mg alloy volatilizes and another dissolves with copper into iron, but the remained Cu-Mg alloy becomes insoluble to the iron and disperses in the form of small liquid particles in the molten iron. On adding silicon to this state of iron, carbon separates out from the melt on the boundary of particles and molten iron. In this case, if the particles are very small, graphite covers the particles and becomes spherical. If the particles are pretty large, the separated graphite grows towards the interior of particles, and is spherodized by being covered with the Cu-Mg alloy.
