US Patent:

40434982, Aug 23, 1977

Filed:

Sep 15, 1975

Appl. No.:

5/613223

Inventors:

Charles E. Conn - Santa Ana CA

Assignee:

TRE Corporation - Beverly Hills CA

International Classification:

B23K 1900

US Classification:

228265

Abstract:

The present invention relates to a method for diffusion bonding metallic detail parts to form a structural component. This invention presents an efficient low cost method of establishing and maintaining the required intimate surface contact for solid state diffusion bonding. This contact is achieved by configuring the metallic details such that sufficient stability is present to permit applying bonding forces sufficiently great to plastic flow the to-be-joined surfaces into intimate contact. The self-stability of the detail parts eliminates the need for support tooling and the plastic flow to achieve intimate contact eliminates the need for close tolerance preparation of the detail parts. This method is particularly applicable to the fabrication of hollow internally stiffened structural components in which the shell skins are non-parallel; such as turbofan/turbojet engine vanes and blades.

International Classification:

B23P 1504
B23K 3100

US Classification:

291568B

Abstract:

The present invention is a lightweight, internally stiffened aerodynamic shell structure with local fittings and a method for fabricating the same. Two typical type structures are the blades and vanes of a turbo fan engine. The invented structure exhibits heretofore unattainable strength and stiffness to weight ratios and a high degree of structural integrity. It is, therefore, particularly advantageous in applications such as the rotating blades in airborne or ground power conversion equipment. It is an aerodynamically shaped structure comprising metallic stiffening material interposed between, and joined to, a pair of relatively thin corresponding metallic face sheets which form the shell skin of the structure. As a function of design requirements, a root fitting, shroud fitting, and tip rib or fitting are solid-state diffusion bonded to the shell structure. In addition, the leading and trailing edges of the shell structure are formed by the solid-state diffusion bonding of the edges of the corresponding face sheets.

TRE Corporation - Beverly Hills CA

International Classification:

B23K 3102

US Classification:

228125

Abstract:

The present invention is a method for constructing a solid state diffusion bonded connection which is homogeneous, capable of efficiently transmitting stress and capable of being analyzed. The method provides for the achievement of homogeneous filleted junctures which are required by long-life structural fatigue specifications. The method also provides a mechanical interlock feature which produces a fail-safe connection. By the invented method, only the amount of material required to form the desired structural connection is used. The members to be joined are cut from sheets or plates of a wrought alloy such that a predetermined amount of metal is available to produce the diffusion bond and specified filleting. Minimum force is required to produce the connection since only localized plastic flow diffusion bonding is required in the vicinity of the juncture of the members. The formed connection is homogeneous and has the same properties across the connection as the parent material.
