Environmentally Assisted Cracking EAC susceptibility and threshold performance of compromised Aluminum 2219 alloy analysis

The National Aeronautics and Space Administration (NASA) is seeking a contractor to perform an analysis of the Environmentally Assisted Cracking (EAC) susceptibility and threshold performance of compromised Aluminum 2219 alloy. The contractor will be required to determine the EAC kinetics of the alloy in various environments, evaluate the loading rate sensitivity, and conduct fractography on test coupons. The contractor will also provide advisory role on fracture mechanics modeling techniques and root cause and fault tree closure. The period of performance is from February 2026 to July 2027. Key aspects of the job include: • Determine the EAC susceptibility and threshold performance of compromised Aluminum 2219 alloy • Evaluate the EAC kinetics of the alloy in various environments • Conduct fractography on test coupons • Provide advisory role on fracture mechanics modeling techniques and root cause and fault tree closure • Travel to various locations to support a HALO Module Corrosion Tiger Team Investigation (if required)
