Fit reasons
- NAICS alignment with historical contract wins in similar service areas.
- Scope strongly matches core technical capabilities and delivery model.
Risks
- Past performance thresholds may require one additional teaming partner.
- Potential clarification needed on staffing minimums before bid/no-bid.
Next steps
Validate eligibility requirements, assign capture owner, and schedule partner outreach to confirm teaming strategy before submission planning.
Quick Summary
NASA/NSSC intends to issue a sole source contract to the Rector and Visitors of the University of Virginia for Environmentally Assisted Cracking (EAC) susceptibility and threshold performance analysis of compromised Aluminum 2219 alloy. This effort is critical for understanding material performance in specific environments. Other interested organizations may submit capabilities for consideration by March 6, 2026.
Scope of Work
The requirement focuses on evaluating the EAC susceptibility and threshold performance of compromised Aluminum 2219 alloy, specifically focusing on ambient condensation environments. Key tasks include:
- Evaluating EAC kinetics and susceptibility of Aluminum 2219 coupons in various environments (e.g., dry nitrogen, 3.5% NaCl immersion).
- Assessing crack tip plasticity effects and conducting crack tip electron back scatter detection (EBSD).
- Evaluating loading rate sensitivity and conducting fractography on all tested coupons.
- Determining the mechanism for EAC in the specified alloy.
- Providing an advisory role on fracture mechanics modeling techniques (expected 3 times per month) and root cause/fault tree closure.
- Optional travel to support a HALO Module Corrosion Tiger Team Investigation.
