Phase 1 SBIR

Agency: Air Force
Topic: AF04-139
Budget: 03/12/04 - 12/12/04

Split sleeve cold working has been used for many years to enhance fatigue and crack growth life of holes. Holes cold worked in high strength aluminum alloys such as 7050 and 2297, however, have shown a tendency to crack in the short transverse grain direction, as reported by Burt and Minarecioglu. They showed that these cracks are the result o...
