Computational Modeling aided Near Net Shape Manufacturing for Aluminum Alloys

Completed TRL 4 (started at 3, targeting 4)

Description

This program will focus on developing and validating computational models for near-net shape processing of aluminum alloys. Computational models will be developed for deformation modeling and for texture generation. Characterization of two aluminum alloys including flow stress, forgeability, and recrystallization characteristics will provide input for the models. The models will be validate through laboratory scale testing of the ring rolling process. The two aluminum alloys are 2139, which has time strength and fracture toughness and ATI451a variant of 2139 that has excellent T6 temper properties. The models will be used to simulate full scale deformation and predict the nonisentropic material properties of the deformed product. Successful completion of this effort will enhance NASA's ability to implement near-net shape manufacturing processes, evaluate new materials and reduce the cost and weight of space exploration vehicles.

How to get involved

This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

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.
