Phase 1 SBIR

Agency: Department of Energy
Topic: 2009
Budget: 01/01/09 - 12/31/09

Stress corrosion cracking (SCC) and fatigue can dramatically reduce the service life of light water reactor (LWR) components, including pressure vessels, steam generator nozzles, pressurized nozzles, and surge lines. Residual tensile stresses, generated from welding and fit-up, are significant contributors to SCC and fatigue failure. The intro...

Phase 1 SBIR

Agency: Navy
Topic: N05-026
Budget: 04/01/05 - 10/01/05

Although surface treatments like low plasticity burnishing (LPB) and laser shock processing (LSP) impart deep compressive residual stresses that significantly improve damage tolerance, credit for the improved fatigue strength is not generally taken in design. The analytical tools needed to support taking design credit by predicting the fatigue l...

Phase 2 SBIR

Agency: Air Force
Topic: AF02-113
Budget: 05/07/03 - 09/07/06

The feasibility of improving damage tolerance of the F119 4th stage compressor IBR blades with low plasticity burnishing (LPB) was successfully demonstrated in Phase I. Fatigue results for Ti-6246 blade-edge specimens showed LPB completely mitigated FOD up to 0.03 in. deep and provided an endurance limit above the Kt=3 design limit for massive F...

Phase 2 SBIR

Agency: National Aeronautics and Space Administration
Topic: 99-2
Budget: 01/01/99 - 12/31/99
PI: Unavailable

Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 98-1
Budget: 01/01/98 - 12/31/98
PI: Unavailable

Phase 1 SBIR

Agency: Department of Commerce
Topic: 1997
Budget: 01/01/97 - 12/31/97

Finish machining of structural ceramics can produce residual stresses, and subsurface defects (SSD) acting as stress concentrators, in the near-surface material. Residual stresses and SSD produced by machining affect the mechanical properties of ceramic components. In this context, it is essential that the residual stresses be properly quantifie...
