Abstract
A weld filler is proposed which significantly improves the weldability of some nickel-based superalloys and includes the following constituents (in wt %): 11.2%-15.6% chromium (Cr), 9.6%-11.4% cobalt (Co) 2.4%-5.0%, molybdenum (Mo) 0.1%-3.3%, 4.4%-7.5% tungsten (W), 1.4%-2.6% tantalum (Ta), 3.0%-4.8% aluminum (Al), 0.4-1.0% titanium (Ti), 0.07%-0.08% carbon (C), 0.5%-1.4% hafnium (Hf), trace elements, and remainder nickel. A method is also provided. The method includes providing a nickel-based substrate to weld, applying a ductile weld filler having a closely matched coefficient of thermal expansion to a surface of the substrate, applying heat to melt the weld filler to form molten weld filler, welding the substrate with the weld filler at ambient temperature, and resolidifying the molten weld filler to form a solidified joint material.
