L-PBF GRX-810 Heat Treatment and Temperature Impact on Very High Cycle Fatigue Study

NASA's Shared Services Center has issued a sole source special notice for an L-PBF GRX-810 Heat Treatment and Temperature Impact on Very High Cycle Fatigue Study to be awarded to the University of Toledo. This procurement involves a 12-month laboratory-based experimental study focusing on laser powder bed fusion additive manufacturing materials testing. The work will support NASA Marshall Space Flight Center's critical mission requirements for the Space Launch System (SLS), Space Technology Mission Directorate (STMD), and commercial space missions. The contract falls under NAICS code 611310 for educational institutions and will follow FAR Part 12 and Part 13 procedures for commercial items. NASA has determined this as a sole source requirement due to the University of Toledo's unique capabilities and established partnership history.

The primary objective is to evaluate the effects of Hot Isostatic Pressing (HIP) and surface finish on GRX-810 specimens through ultrasonic fatigue testing at temperatures up to 1000°C, supporting NASA's Game Changing Technology "Integrated Rotating Detonation Engine Systems" program. The University of Toledo must receive, machine, and test 60 specimens within 20 weeks, delivering a final test report, PowerPoint summary, and comprehensive digital data to NASA Marshall Space Flight Center. Interested organizations may submit capability statements and qualifications in writing to the Point of Contact by 7:00 AM Central Standard Time on July 28, 2025, though the government retains discretion over whether to conduct competitive procurement. The sole source justification emphasizes the University of Toledo's specialized ultra-high cycle fatigue testing equipment capable of operating up to 2400°F and their subject matter expertise that ensures data integrity and continuity. Changing vendors would potentially result in testing inability and schedule delays exceeding 12 months, making this procurement critical for maintaining research continuity.
