Micro Segregation of TC11 Alloy Ingot
The micro segregation in TC11 was studied, the rule of micro segregation in TC11 was obtaied. The results show that, in equiaxed grains and columnar grains, the contents of Al and Mo decrease along the directions of the grain growing, but the contents of Zr and Si increase; because of the effects of segregation in the solidification, the micro segregation of the four elements in the equiaxed grains is higher than that in the columnar crystals; Al and Zr are rich on grain boundaries, but Mo and Si are rich in grains.
