Abstract
The disclosure relates to a turbine disk and a method of making the turbine disk comprising the steps of rotating a mold, adding a first powdered metal to the rotating mold at a first rate, reducing the rate of addition of the first metal to a second rate, and adding a second powdered metal to the mold at a third rate substantially equal to the difference between the first and second rates.
