About this file
This Statement of Work (SOW) details NASA Marshall Space Flight Center's requirement for the University of Toledo to conduct a laboratory-based experimental study on L-PBF GRX-810 heat treatment and its impact on very high cycle fatigue (VHCF). The primary objective is to evaluate the effect of Hot Isostatic Pressing (HIP) and surface finish on GRX-810 specimens through ultrasonic fatigue (USF) testing at room and elevated temperatures up to 1000°C.
The vendor must receive, inspect, track, and machine 60 specimens according to specific drawings, perform mechanical testing within 20 weeks, and complete post-test fractographic characterization. Deliverables include a final test report in journal article format, a PowerPoint data summary, digital data (CSV/Excel) of stress/strain and hysteresis, and raw data including hysteresis curves. All deliverables and samples will be shipped to NASA Marshall Space Flight Center in Huntsville, Alabama. The study supports NASA's Game Changing Technology "Integrated Rotating Detonation Engine Systems" and Space Launch System (SLS) Liquid Engines Office projects.

L-PBF GRX-810 Heat Treatment and Temperature Impact on Very High Cycle Fatigue Study
Statement of Work (SOW)
NASA Marshall Space Flight Center (MSFC) requires the ability to conduct laboratory-based experimental tasks. The University of Toledo (UToledo) has several unique capabilities that distinguish it from other institutions in evaluation of fatigue behavior of materials with unique fatigue testing capability, a broad range of material characterization facilities, and subject matter experts familiar with NASA technical requirements. These stated capabilities are not common to all institutions and this procurement intends to leverage experience gained. These data and specimens are needed for application into Game Changing Technology (GCD) “Integrated Rotating Detonation Engine Systems” and Space Launch System (SLS) Liquid Engines Office (LEO) projects.
Task 1: Evaluation of L-PBF GRX-810 in VHCF Regime The objective of this task is to evaluate effect of HIP and surface finish on GRX-810 specimens in the very high cycle fatigue (VHCF) regime.
1. The vendor shall receive all samples and inspect samples numbers.
2. The vendor shall track all samples (ie., bag and tag samples) in preparation for machining.
3. The vendor shall machine and perform mechanical testing of all samples according to a matrix provided below.
4. The vendor shall complete all machining, mechanical testing (fatigue) within 20 weeks of receiving all samples at their site.
5. The vendor shall have experience testing materials using ultrasonic fatigue (USF) testing at room and elevated temperatures up to 1000°C.
6. The vendor shall have experience testing NASA oxide dispersion strengthened (ODS) alloys and preparation of samples for unique surface texture requirements and provide evidence of compatible data.
7. The vendor shall complete machining and grinding of all ultrasonic fatigue (USF) specimens, according to drawings “USF_Hourglass” for room temperature and elevated temperature testing. Samples are ~10mm diameter and ~54mm length. Machining shall be controlled to meet all dimensions.
8. Vendor shall complete USF testing at room and elevated temperatures up to 1000°C on
(60) specimens according to establish testing methodology.
9. Test overruns for VHCF should be reported to NASA for early awareness to allow adjustments as necessary.
10. Vendor shall complete post-test fractographic characterization and analysis of room and elevated temperature specimens and complete summary of data in addition to fractographic analysis.
11. Vendor shall provide updates on fatigue testing to allow adjustments to conditions if necessary.
12. Vendor shall provide final report (in form of journal article) and summary slides.
13. The vendor shall provide updates on any characterization of provided specimens before and after testing.
14. NASA will provide detailed test matrices and discuss as necessary.
