Effect of Trace Elements on the Properties of Gray Cast Iron
Год выпуска: 2014 Автор: Kandula Ankamma Издательство: LAP Lambert Academic Publishing Страниц: 60 ISBN: 9783659588181 Описание 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...
