Abstract
A turbine component and a process of fabricating a component are disclosed. The process includes excavating a base metal of the component to form a fill region and filling the fill region with a filler metal. The filler metal has a filler metal elongation that is at least 25% greater than a base metal elongation of the base metal. The filler includes, by weight, between about 4% and about 7% iron, between about 14% and about 17% chromium, between about 15% and about 17% molybdenum, between about 3% and about 5% tungsten, up to about 0.02% carbon, up to about 1% manganese, up to about 2.5% cobalt, and a balance of nickel and/or the filler metal elongation is greater than about 35% in/in per two inches.
