Abstract

A superalloy powder mixture is provided for use with additive manufacturing or welding metal components or portions thereof. The superalloy powder mixture includes at least 51% by weight a high melt superalloy powder and at least 5% by weight a low melt superalloy powder. The low melt superalloy powder may have a solidus temperature lower than the solidus temperature of the high melt superalloy powder by between 50° C. and 220° C. 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 may 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.
