High Temperature Oxide Dispersion Strengthened (ODS) Alloy Mechanical Testing

Summary (Newest Update)

Background The National Aeronautics and Space Administration (NASA), specifically the Marshall Space Flight Center (MSFC), has a requirement for mechanical testing of unique NASA-developed alloys. The goal of this contract is to validate material properties for design through independent laboratory testing of High Temperature Oxide Dispersion Strengthened (ODS) Alloy. Work Details The vendor shall perform the following tasks: 1. Receive and inspect all samples. 2. Track samples by bagging and tagging them in preparation for machining. 3. Machine and conduct mechanical testing of all samples according to a provided matrix. 4. Complete all machining and mechanical testing (fatigue) within 16 weeks of receiving samples. 5. Maintain Nadcap and A2LA (ISO/IEC 17025:2017) accreditation for ASTM E8/21 and E606/E466 standards. 6. Have experience with ODS alloys including GRX-810, ORCAlloy-21, and Alloy 754-ODS, along with compatible data. 7. Prepare tensile specimens according to E8/E21, providing a minimum of 165 fully machined samples for tensile testing. 8. Machine and grind low cycle fatigue (LCF) specimens (75 total) per ASTM E606 geometry, using specified drawings for elevated and room temperature specimens (~0.55” diameter, 3.25” length). 9. Conduct low cycle fatigue testing at temperatures up to 2100F on LCF specimens according to ASTM E606. 10. Perform tensile testing on 65 room temperature samples per ASTM E8 and on 100 samples at temperatures up to 2100F per ASTM E21. 11. Machine and grind high cycle fatigue (HCF) specimens (75 total) according to ASTM E606 geometry, ensuring dimensions are met (~0.6” diameter, ~4” length). 12. Conduct high cycle fatigue load control testing at temperatures up to 2000F on HCF specimens according to ASTM E466. 13. All machining and testing must be performed onsite; subcontracting is not allowed without NASA approval for any offsite work. 14. Report test overruns for LCF and HCF to NASA promptly for awareness and adjustments as necessary. 15. Provide updates on fatigue testing conditions as needed, with NASA supplying detailed test matrices. Period of Performance The contract will be performed over a period of approximately 16 weeks from the receipt of all samples. Place of Performance The work will be conducted onsite at the vendor's facility holding the contract.
