Additively Manufactured Ti64 and Ni718 Very High Cycle Fatigue Test Bars

NASA’s Marshall Space Flight Center requires the fabrication, post‑processing, and delivery of additively manufactured GRCop‑42 test specimens to support very‑high‑cycle fatigue and thin‑wall tensile testing for rotating detonation engine components. The vendor must produce the full specimen matrix (including HCF bars, RT USF bars, elevated‑temperature USF bars, blank cylinders, and tensile coupons) in accordance with dimensions and models supplied by MSFC engineers, ensuring parts are free of witness lines, restarts, or coater‑arm tears. All build anomalies must be reported to the MSFC technical point of contact, and a basic build package—including process‑validation data and powder pedigree documentation compliant with AS9100, ISO‑9001, or an equivalent standard—must be provided. Post‑processing includes de‑powdering, removal from the build plate via electrical discharge machining, vacuum nucleation, and hot isostatic pressing by an agreed vendor. Completed specimens and documentation are to be shipped to Central Receiving, Bldg 4631, NASA MSFC, Huntsville, AL. The entire effort must be completed within six (6) weeks of contract award.
