The effect of heating rate on phase transformations to austenite range in ductile cast iron of the EN-GJS-450-10 grade was investigated. For studies of phase transformations, the technique of differential scanning calorimetry (DSC) was used. Micro structure was examined by optical microscopy. The calorimetric examinations have proved that on heating three transformations occur in this grade of ...

INVESTIGATION OF DUCTILE IRON IN MOLD TREATMENT

Ductile iron was first developed in 1943 and it is widely used in automotive industry. The difference between cast iron and ductile iron is due to the presence of spheroid graphite in the matrix of ductile iron which is not found in brittle cast iron. Ductile iron possesses higher ductility and tensile strength than in cast iron.
