Comparative Study of Pressure Casting and Centrifugal Casting on Molten Titanium Flow

Abstract

One of the determining factors governing the titanium flow in a mold cavity is the intensity of the casting force, including its direction. Actual casting force is the pressure applied to the narrow orifice of the cavity even in the case of the centrifugal casting. The filling areas and flow nature were observed by X-ray radiographs and flow patterns became apparent on tracer (Pd) distribution maps. The results of these experiments proved that the most significant factor influencing flow behavior in the mold cavity is the intensity of the body force, the gravity or the centifugal force. Furthermore, external and internal defects in the titanium castings are also influenced by this factor.
