Book Description
Volume is indexed by Thomson Reuters CPCI-S (WoS). Cast iron, one of the oldest alloys known to the human race is still finding new applications in spite of fierce competition from lighter alloys as well as from the most recently discovered new materials. From its earliest beginnings in around 500BC, cast iron underwent little change until the revolutionary development of spheroidal-graphite (ductile) iron in 1949. This discovery was the spark that ignited a series of unexpected transmogrifications of that ancient alloy.After three centuries cast iron is still, surprisingly, widening its scope of application; thanks to the dedicated research work that has been carried out over the past few decades.

Book Description
The present work correlates the effect of trace elements (Boron, Lead, Bismuth and Titanium) on the tensile strength, hardness and microstructure of gray cast iron. These elements have a significant effect on the properties and microstructure of gray cast iron. These elements are deliberately added to study their effect on properties and microstructure. Boron up to 0.02% in gray cast iron showed an improvement in tensile strength and hardness values. While beyond this amount it shows a decreasing trend, due to the formation of type B and D graphitic structure. Lead in gray cast iron shows a decreasing trend in tensile strength and hardness values, even if present in trace amount, due to the formation of spiky or mesh type graphite. Bismuth also shows a decreasing trend in tensile strength and hardness values for all additions. Titanium up to 0.05% has shown a decrease in tensile strength and hardness values, while beyond this amount the properties are slightly improved. The source of trace elements into gray cast iron are mainly due the charge material i.e from pig iron, non-ferrous metal scrap, vitreous enameled scrap, leaded steel scrap, purchased scrap containing lead.

Book Description
In their bid to produce cast iron latter than Malleable Iron, the scientist discovered the ductile iron or S.G. Iron (spherodial Graphite iron) way back in 1948. The use of this type of cast iron as an engineering material has been increasing day by day ever since its discovery. It is now replacing steel in many important engineering applications. The production of S.G Iron increased to a large extent during last two decades. The excellent combination of mechanical properties obtained in S.G. iron can further be informed by the heat treatment. The most recent development in this regard is the production of Austempered Ductile Iron (ADI). It provides an excellent combination of high tensile strength, wear resistance along with good corrosion resistance and quite significant amount of ductility. Due to these factors, S.G. or ductile iron are austempered when a very favourable combination of various properties is required. But this type of treatment is bit tricky, since it require controlled heating and isothermal holding of the material. So it is necessary to find some attractive methods for property development in S.G. iron. In the present work conventional heat treatment proceeds like annealing, normalizing and tempering of the material has been performed. The mechanical properties obtain by various technique have been compared to one another. In this work two different grades of S.G. Iron (one with copper and another without copper) have been used. The effect of the alloying element (i.e. copper) has also been studied.
