Abstract
The segregation of Ti-2.5Cu, Ti-3Fe and Ti-3Cr in Ti-alloy ingots has been studied. It was found that in equiaxed grains, segregation of Cu and Fe is obvious and segregation of Cr is slight. In columnar grains, segregation of Cu, Fe, and Cr is slight. In both cases the contents of Cu, Fe, and Cr increase along the directions of grain growing. It is rich in Cu and Fe in grains; but it is rich in Cr at grain boundaries. In the bulk it is rich in Cu, Fe and Cr on the top and radial zone of the ingots.
