Single roll method for foil casting of the aluminum alloy

In order to cast rapidly solidified aluminum alloy foil with sound free solidified surfaces, two types of single roll processes were developed in the present study. Reduction of the puddle size is required in order to produce a free solidified sound surface. Therefore, the present study examines the effects of various casting factors that have not been investigated in previous studies: these are the ejection angle of the melt and the break of the melt. The results of the present study indicate that foils cast using the proposed processes are superior to those cast using planar flow casting (PFC), a conventional single roll rapid solidification process.
