Filed:

May 8, 2001

Appl. No.:

09/851596

Inventors:

Tracey W. Nelson - Provo UT 84601

International Classification:

B23K 2012

US Classification:

2281121, 228 21, 228 23, 228113, 2281145

Abstract:

A probe for friction stir welding MMCs, ferrous alloys, non-ferrous alloys, and superalloys, as well as non-ferrous alloys, the probe including a shank, a shoulder, and a pin disposed through the shoulder and into the shank, wherein the pin and the shoulder at least include a coating comprised of a superabrasive material, the pin and shoulder being designed to reduce stress risers, disposing a collar around a portion of the shoulder and the shank to thereby prevent movement of the shoulder relative to the shank, and incorporating thermal management by providing a thermal flow barrier between the shoulder and the shank, and between the collar and the tool.

Inventors:

Tracy W. Nelson - Provo UT
Carl D. Sorensen - Provo UT
Scott M. Packer - Alpine UT

Assignee:

Brigham Young University Technology Transfer Office - Provo UT

International Classification:

B23K 2012

US Classification:

228 21

Abstract:

A friction stir welding anvil and method of producing a friction stir welding anvil that precludes diffusion or mechanical bonding of the anvil to the work pieces are provided. The alternatives for producing such an anvil comprise coating the anvil with diffusion barriers such as oxides, nitrides, intermetallics, and/or refractory metals; manufacturing an anvil either completely or partially from the same; or placing a coating of such materials in the form of a thin sheet or a powder between the anvil and the work pieces. The anvil disclosed herein exhibits high strength and hardness even at elevated temperatures, such as those greater than 800Â C. , so as to prevent the anvil from mechanically or diffusion bonding to the work pieces and so as to minimize, or eliminate altogether, anvil deformation.

International Classification:

B23K 20/12

US Classification:

2281121

Abstract:

The present invention relates to a method of joining segments of high melting temperature materials, that includes frictionally heating a first high melting temperature material and a second high melting temperature material wherein the first high melting temperature material and second high melting temperature material are welded together, without substantially changing the macrostructure and/or the microstructure of the first high melting temperature material and the second high melting temperature material, after application of a frictional force.
