摘要： A multi-component braze filler alloy comprising at least 70% by weight MarM509A superalloy with the remainder MarM509B superalloy is diffusion brazed to a CM247 alloy base substrate, such as a gas turbine blade or vane. It is shown that generally higher braze temperatures lead to improved results including the possibility of re-welding such a brazed component, resulting in a re-repaired brazed component capable of continued commercial service.

摘要： A multi-component braze filler alloy comprising 60-70% by weight CM247 superalloy and BRB braze alloy is diffusion brazed to a CM247 alloy base substrate, such as a gas turbine blade or vane. The substrate/braze interface may be subsequently weld-repaired without de-melting and migrating the braze alloy from the interface. The weld zone and surrounding area are solidification crack resistant. After the alloy composition is brazed to the base substrate the component may be returned to service. Thereafter the component remains repairable by welding or re-brazing, if needed to correct future in-service defects.
摘要翻译： 包含60-70重量％CM247超合金和BRB钎焊合金的多组分钎焊填料合金被扩散钎焊到诸如燃气轮机叶片或叶片的CM247合金基底衬底。 衬底/钎焊界面可以随后进行焊接修复，而不会使熔融和钎焊合金从界面迁移。 焊接区及周边区域均具有抗凝固性。 在合金组合物钎焊到基底材料之后，可以将组分恢复使用。 此后，如果需要修复未来的在役缺陷，则该部件可以通过焊接或再钎焊来维修。
