Abstract: PROBLEM TO BE SOLVED: To provide a method for repairing parts such as a rotary disc/ drumrotor of a gas turbine engine. SOLUTION: This method includes steps for: heating a contact area 207 of a forged material and a contact area 307 of forged parts; pressurizing the contact area 207 of the material to the contact area 307 of the parts to joint them. A method for producing rotary parts of the gas turbine engine includes a step for heading the contact area 207 of the forged material and the contact area 307 of the forged parts, and a step for pressurizing the contact area 207 of the material to the contact area 307 of the parts to joint them. This method may include a sequential heat treatment step for giving a desired strength characteristic to a joint part 309 between the material and the parts. COPYRIGHT: (C)2003,JPO

Abstract: NON-INVASIVE THERMAL MANAGEMENT PROCESSES FOR RESTORATING METALLIC DETAILS BONDED TO SUBSTRATES A thermal management process for enabling the restoration of a surface of a metallic detail in the presence of at least one bonding material, comprising preparing at least one damaged area on a metallic detail; disposing at least one thermal management component upon a bonding material or a surface area proximate to the bonding material to which the metallic detail is joined; masking at least the surface area and the bonding material with a masking agent; and dimensionally restoring a surface of the metallic detail disposed on the article at a processing temperature lower than a temperature which would degrade the bonding material, the substrate, or the bondment interface therebetween.

Abstract: METHOD OF JOINING MATERIAL A method of repairing a part, such as a rotating disk/drum rotor of a gas turbine engine. The method includes: heating a contact area of a wrought material and a contact area of a wrought part; and pressing the contact area of the material against the contact area of the part to bond the parts. A method of making a rotating part of a gas turbine engine, comprising: heating a contact area of a wrought material and a contact area of a wrought part; and pressing the contact area of the material against the contact area of the part to bond the parts. The methods may include a subsequent heat treatment to provide the desired strength properties to the joint between the material and the part. Figures 6 and 7

Abstract: In the repair or replacement of vane assembly retaining lugs, a replacement lug of a wrought alloy is solid state bonded to the vane assembly in place of the previous retaining lug. The existing lug is first removed from the assembly to leave a stub portion which is machined to form a surface to which a replacement lug may be bonded. A replacement lug blank is then positioned adjacent the stub face, a vacuum drawn in that region and a bonding force applied, the interface between the stub and replacement blank being heated locally. After bonding the assembly is heat treated and the replacement lug machined to a desired configuration.

Abstract: A hole in a metal component such as a gas turbine rotor flange (3) of superalloy or titaniurn is repaired by enlarging the hole to a uniform diameter (5), inserting a plug (6), of the same or similar material and heat treatment in the enlarged hole (5) and applying sufficient pressure (9,10) to the plug and heating the plug and the surrounding material to forge join the plug and the walls of the hole whereby a fully recrystallized joint interface is achieved between the plug and the walls of the hole. Excess material is removed.

Abstract: A joint between two metallic materials obtainable by carrying out a process comprising the steps of: providing two metal members (12,14) and a prealloyed interlayer foil (16); creating a joint interface by positioning said foil (16) between said members (12,14); applying a load transverse to said joint interface. Said process further comprises a step of applying localized, rapid heating in the area of said joint interface at a temperature which effects bonding of said members (12,14) while causing no degradation of microstructural or mechanical properties of the metal and a coarsening of grains in rim portions of said members (12,14) so as to form creep resistant rim portions.
