Abstract:
SGI Casting is most important Casting process. As specially SGI Casting is Graded Casting so it is difficult to maintain all composition. Spheroidal graphite iron castings has been increasing constantly all over the world. In the recent years there has been increasing interest in the microstructure analysis of SGI castings. So analyze the Alloying elements effect on the microstructure particularly nodularity of SGI 400/15 grade material and also effect of solidification time on nodularity.
