    摘要: The bonding of materials by the transient liquid phase process is improved through the use of multiple boronized interlayer foils. By providing the interlayer in the form of multiple foils a reservoir of liquid material is formed during the bonding process which eliminates the previously encountered porosity. The use of multiple foils is especially appropriate when bonding fine grained materials.

    摘要: Disclosed is an improved method and apparatus for removing damaged or worn vanes which are brazed or otherwise metallurgically attached between the concentric inner and outer shroud members of a gas turbine compressor stator. The method involves punching one of the attached vane ends in the radial direction relative to the concentric shroud members with sufficient force to shear the metallurgical joints holding the vane in the shroud slots. During punching, the shroud members are rigidly supported against deformation in the vicinity of the attached vane ends and the vane itself is supported laterally to prevent buckling thereof. With the invention, a stator can be repaired with no diminution in structural strength as compared to a new part. A punch and die assembly for use in removing a damaged vane is also disclosed.
