Characteristics of two Al based functionally gradient composites reinforced by primary Si particles and Si/in situ Mg2Si particles in centrifugal casting ZHAI Yan-bo(翟彦博), LIU Chang-ming(刘昌明... functionally gradient composite tubes reinforced by primary Si particles alone and primary Si/ in situ Mg2Si particles jointly were successfully prepared by centrifugal casting, and their structural......
to describe the filling and solidification of TiAl melt by permanent mold centrifugal casting. The model was solved numerically and the filling and solidification processes in the centrifugal field were...]. However, for centrifugal casting TiAl valves, the horizontal cavity is a certain distance away from the vertical axis and rotates round it, which leads to an entirely different filling......
