Characterization of GRCop-42 Additively Manufactured Material (CSCO-2017-03) -- Extended Investigation
Completed
Description
The overall goal of the second phase of this study is to complete material property testing on a dispersion strengthened copper-alloy, GRCop-42, to determine optimal directed energy deposition (DED) manufacturing parameters. Previously, this material has been extensively studied in non-additive manufacturing methods and by powder bed fusion AM. In the initial phase of this project, our team has learned how to conduct all the testing to match procedures and methods used in previous NASA studies so the test results can be compared. In addition, we have begun testing using other techniques not previously studied (nanoindentaion, LXRD for residual stress, CT scanning, etc.). Currently, a large batch of tensile samples are being tested at room temperature and incrementing up to 800C. Samples were cut in both major direction of the manufacturing process to test anisotropy.
In the second phase of the project, we will continue testing new manufacturing parameters of DED GRCop-42 using the same techniques as learned in the first phase. In addition, we will add low/high cycle fatigue testing as material samples are provided. By the end of phase two, we will have a basic understanding of how DED manufacturing parameters affect overall part quality and how to tailor material properties according to manufacturing parameters.

How to get involved
This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
