Abstract
A method of repairing or manufacturing a superalloy component (50) by depositing a plurality of layers (22, 24, 26, 28) of additive superalloy material having a property that is different than an underlying original superalloy material (30). The property that is changed between the original material and the additive material may be material composition, grain structure, principal grain axis, grain boundary strengthener, and/or porosity, for example. A region (60) of the component formed of the additive material will exhibit an improved performance when compared to the original material, such as a greater resistance to cracking (58).
