Abstract: A nickel-based polycrystalline alloy comprising 0.03-1.9 % hafnium, 0.003-0.32 % boron, 0.02-0.16 % yttrium and 0.007-0.35 % zirconium is disclosed. A method of repairing nickel-based superalloy substrates using the above-described alloy is also disclosed. The present invention further provides a method for the repair of single crystal alloy substrates by the application of a repair alloy wherein the repair alloy's composition is similar to or the same as the single crystal alloy composition except that the repair alloy additionally comprises grain boundary strengtheners and/or oxidation resistance enhancers.
Abstract translation: 公开了一种镍基多晶合金，其包含0.03-1.9％的铪，0.003-0.32％的硼，0.02-0.16％的钇和0.007-0.35％的锆。 还公开了使用上述合金修复镍基超合金基板的方法。 本发明还提供了一种通过使用修补合金修复单晶合金基板的方法，其中修补合金的组成与单晶合金组合物相似或相同，除了修补合金另外包括晶界强化器和 /或抗氧化增强剂。
