摘要：

In the present work an effort has been made to correlate the “Effect of trace elements (B and Pb) 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 type 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. © 2014, The Author(s).
