Cast Iron is being used in various Industries like Automotive, Agriculture, Construction etc., for many decades. Metal casting processes have its unique advantages like ease of heavy weight castings, intricate shapes, higher productivity. Commercially viable (low cost) etc., using wide range of materials like Gray cast iron, Spheroidal cast iron, Malleable cast iron ,cast steel etc., Cast iron have an excellent properties like high dampening capacity, higher thermal conductivity, wear resistance required by many critical applications. These unique combinations will be chosen to serve the purposes both functionally and commercially. However, in last one-decade automotive and agriculture industries are facing issue of fuel economy which directly influenced by the weight of the vehicle. For off-road vehicle like tractors, One of the major contributor in vehicle weight is cast iron. Many material grades and strengthening mechanisms are recently being evolved to optimize the cast iron material performance. In this study, the influence of casting section thickness on the microstructure and hardness of newly developed Ferritic solid solution strengthened ductile iron have been studied with standard sample. Co-relation coefficient studied with multiple samples which in turn casting thicknesses are no more an influencing factor in ferritic solid solution strengthened cast iron w.r.t hardness, nodule count, and microstructure
Keywords: solid solution ferritic strengthening, co-relation of hardness and microstructure,
