Prediction And Experimental Study On Surface Roughness Of Stepped Austempering Gray Cast Iron Using Artificial Neural Network

A novel stepped austempering process has been widely used for improving of mechanical properties of cast iron. Although most of the stepped austempering process focused on ductile iron, only minimal study has been carried out in gray cast iron. In this study, the effects of stepped austempering on the surface roughness of gray cast iron. Mathematical model developed for prediction of surface roughness with Artificial Neural Network (ANN). Experimental result showed that stepped austempering heat treatment significantly influences the surface roughness of gray cast iron. In addition, artificial neural network model provide highly accurate and consistent prediction for all surface roughness.
