PROBLEM TO BE SOLVED: To provide heat resistant alloy for high temperature applications such as constituents for gas turbine-engine in aircraft engine and power generation equipment, and to provide a method for repair of an article for high temperature application. SOLUTION: The alloy for use in high temperature comprises, by atom, at least about 50% rhodium (Rh), at least about 5% of metal selected from among the group consisting of platinum (Pt), palladium (Pd) and combination thereof, about 5 to 24% ruthenium (Ru) and about 1 to 40% chromium (Cr). , wherein the alloy comprises less than about 50% by volume of an A3 structured phase, and wherein the quantity defined by the expression of ([Cr]+2[Ru]) lies in the range of about 25 to 50% (where, [Ru] and [Cr] are the atomic percentage of ruthenium and chromium in the alloy, respectively). The article comprising the alloy and the method employing the alloy for repairing the article are provided. COPYRIGHT: (C)2005,JPO&NCIPI
