Environmentally Assisted Cracking (EAC) performance of Russian alloy

NASA's Shared Services Center has published a sole source procurement synopsis for a scientific research contract focused on Environmentally Assisted Cracking (EAC) performance testing of Russian alloy AMG6NOP. The agency intends to award this contract exclusively to the Rector & Visitors of the University of Virginia to conduct specialized materials testing in unwelded conditions within ambient condensation environments. The work will be performed at NASA Johnson Space Center, with NASA/NSSC serving as the procuring center. This procurement is classified under NAICS Code 611310 for educational institutions and will utilize commercial items and services procedures. The contract represents Phase 4 of an ongoing research program examining the performance characteristics of Russian aerospace materials.

The primary objective of this sole source contract is to evaluate the EAC performance of AMG6NOP alloy through comprehensive testing and analysis, including desiccation procedures, kinetics testing at various concentate concentrations, fractography, and advisory support for fracture mechanics modeling. Organizations interested in demonstrating their capabilities must submit written qualifications to the contracting officer by 1:00 p.m. Central Standard Time on September 2, 2025, with oral communications explicitly prohibited. The contract period extends through September 30, 2026, structured as a firm fixed-price arrangement with payment milestones tied to specific deliverables including test plans, status reports, and a final research report. NASA will provide test coupons and expert personnel while the contractor supplies testing equipment, and the agreement includes provisions for an optional international trip to Russia for leak investigation activities. The University of Virginia is specifically restricted from sharing any data related to Russian hardware or materials outside the scope of this project.
