Brazing of Hastelloy X with wide clearance butt joints
- Dayton, University, Dayton, Ohio

Wide-clearance butt joints of Hastelloy X base metal are vacuum furnace brazed by sintering a nickel-base powder of high melting point (sinter filler metal) in the joint, followed by filling the powder interstices with a nickel-base brazing filler metal and a diffusion treatment. A technique is developed for brazing high-quality butt joints with virtually unlimited joint clearance. It is shown that at clearances greater than 6 mils, the use of sinter filler metal produces brazed joints with room-temperature tensile strength far superior to those of conventionally brazed alloys. The application of the sinter filler metal brazing technique to the repair and fabrication of gas turbine components is discussed.
