Abstract
System, methods for improving grain growth in a cast melt of a superalloy are provided. The system includes at least a mold having a shape defining a part of a turbo machine, e.g., a turbine blade. A cast melt, e.g., a superalloy, is poured into the mold, and one or more heating/cooling elements are arranged in the cast melt. The system further includes a controller operatively connected to the elements for controlling the electrical current of, e.g., a heating wire of the heating element, or controlling the flow-rate for, e.g., a coolant of the cooling element. By controlling, i.e., adjusting the current and/or flow-rate, via the controller, a temperature gradient may be induced to improve grain growth.
