Paper Title:
The Solidified Structure and Macrosegregation of Wedge-Shaped Titanium Castings Produced by Vertical Centrifugal Casting Process
  Abstract

The present paper studied the as-cast structure and macrosegregation of the wedge-shaped castings produced vertical centrifugal casting process at different mould rotating speeds. The element distributions were determined by the secondary electron line scanning in the S-570SEM type scanning electron microscope (SEM) and the grain sizes of the castings were observed by the optical stereoscope. The research results show that the grain sizes increase with increasing of casting wall-thickness, but decrease with increasing of the mold rotational speed. The cooling rate is high and rotational speed is not high enough, therefore, there is slightly macrosegregation trend for the alloy element of Al and V in the wedge-shape castings.
