MATHEMATICAL MODELLING FOR SPIRAL FLUIDITY OF AL-SIC MMCs BY DESIGN OF EXPERIMENTS

摘要

In this paper the flow ability of Aluminimum-silicon carbide particulate composite has been studied by using spiral fluidity test. A mathematical model has been developed for maximizing the fluidity. The two parameters taken into consideration for study are % volume of SiC[V] present in the composite and Temperature of pouring[T]. The experiments were conducted at three levels of each parameter. The linear, quadratic and interactive effects of the parameters were estimated. Finally the significance of the developed model was assessed using analysis of variance (ANOVA) technique. With increase in volume of SiC the fluidity decreases non-linearly whereas the increase in temperature has linear effect on fluidity.
