    Abstract: A method of repairing a superalloy component (22) wherein a section (24) of the component containing a plurality of service-induced cracks (18, 20) is removed, then a replacement section (26) of superalloy material is installed with a structural braze joint (28) containing no boron or silicon. The replacement section may have a textured surface ((38) to enhance bonding with an overlying thermal barrier coating (42). The replacement section may be pre-formed to standardized dimensions in expectation of a typical service-induced crack pattern, and the removed section excavated accordingly. The interface between the replacement section and the component may be shaped to provide a mechanical interlock there between.

    Abstract: A class of nickel based alloys having a fine grain structure resistant to stress corrosion cracking, and methods of alloy design to produce further alloys within the class are presented. The alloys act as suitable welding materials in similar applications to that of Alloy 622. The fine-grained structure of these novel alloys may also be advantageous for other reasons as well such as wear, impact, abrasion, corrosion, etc. These alloys have similar phases to Alloy 622 in that they are composed primarily of austenitic nickel, however the phase morphology is a much finer grained structure opposed to the long dendritic grains common to Alloy 622 when it is subject to cooling rates from a liquid state inherent to the welding process.
