  • Publication number: 20160136725
    Abstract: A method for making an equiaxed investment casting. The method utilizes an ultrasonic generator to send an ultrasonic pulse into molten metal in an investment casting mold. The investment casting mold is positioned within a working zone of furnace having low output induction coils for generating a convection current in molten metal. The ultrasonic pulse separates dendrites growing from the face of the mold inward into the molten metal. Instead, equiaxed grains can nucleate within the molten metal. In addition, the ultrasonic pulse and the low output induction coils circulate the molten metal as solute is rejected from solidifying equiaxed grains. The mixing reduces the effects of segregation in the solidifying alloy and assists in nucleating equiaxed grains.

    Abstract: A system and method for controlling processor instruction execution. In one example, a method for synchronizing a number of instructions performed by processors includes instructing a first processor to iteratively execute instructions via a first set of iterations until a predetermined time period has elapsed. A number of instructions executed in each iteration of the first set of iterations is less than a number of instructions executed in a prior iteration of the first set of iterations. The method also includes instructing a second processor to iteratively execute instructions via a second set of iterations until the predetermined time period has elapsed. A number of instructions executed in each iteration of the second set of iterations is less than a number of instructions executed in a prior iteration of the second set of iterations.
