AtandaP.O. 122007717In this study, the effect of processing parameters such as alloy composition and shake-out time on the microstructure and subsequently the mechanical properties of brake drums to the specification of an automobile company had been studied. The results show that processing parameters such as alloy composition (Silicon and Carbon contents) affect the quantity and morphology of the carbides formed while shakeout time affects the size of the carbide. When all other parameters are kept constant, shakeout time of a casting to obtain desired properties can be predicted using a relationship derived from multiple regression analysis in this study work. The relationship is: Shake-out time = -13.8+0.0799Si+6.954GS+0.0467 Hardness.]]>Buni, S.Y., N. Raman and S. Seshan,200429117127Cho, M.H., S.J. Kim, R.H. Basch, J.W. Fash and H.
