Abstract
A method is provided that facilitates additive manufacturing a superalloy component using a liquid assisted additive manufacturing process. The method includes successively depositing and fusing together layers of a superalloy powder mixture comprising a high melt superalloy powder and a low melt superalloy powder to build up an additive portion of the superalloy component. The method may further include heat treating the additive portion to form a homogenized base alloy of which the additive portion is comprised, which base alloy has a chemistry defined by the superalloy powder mixture. Each of the high melt superalloy powder, the low melt superalloy powder, and the superalloy powder mixture may have a nickel content by weight greater than 40% and have an aluminum content by weight of greater than 1.5%. The low melt superalloy powder may include at least 5% by weight of tantalum, and the high melt superalloy powder may include less than half the content by weight percent of tantalum compared to the content by weight percent of tantalum in the low melt superalloy powder.
