Abstract
A gas turbine, copper-based alloy part having a crystalline structure in which grain boundaries are elongated in the direction of principal stress applied to the part when in turbine service exhibits especially enhanced strength and fatigue resistance in such direction. The part is prepared in a process in which it is first cast to shape in a mold and then directionally solidified by substantially limiting the heat flow from the part to a direction parallel to the principal stress direction.
