Effects of addition of iron (Fe) filings to green moulding sand on the microstructure of grey cast iron

Cast irons are important engineering materials, which possess a wide range of attractive properties. Their properties are significantly dependent on the microstructure of the cast, cast iron components. A way of controlling the microstructure of cast iron is through the control of cooling rates during solidification. To control cooling rate mould properties are important. This paper presents the report of a study of the effects of additions of iron filings to green moulding sand on the microstructure of grey cast iron. Five sand samples were prepared with different Fe content ranging from 1 wt...
