TECHNICAL ABSTRACT (LIMIT 200 WORDS)
This STTR Phase I effort proposes to develop an innovative, affordable processing route for larger-sized shape memory alloy (SMA) components. Despite significant advances over the last decade, innovative, cost-effective shape processing techniques yielding controlled microstructure-properties are still needed for SMA's. An advanced reactive metal casting technology is applied in this project to manufacture SMA's. Casting offers a relatively low-cost approach for fabricating near net-shape components, and would allow for widespread acceptance and application due to its cost-effectiveness.

POTENTIAL NASA COMMERCIAL APPLICATIONS (LIMIT 100 WORDS)
Potential NASA commercial applications include aeroengine and airframe structural components, particularly those requiring impact resistance. SMA's are also being considered for flexible wings for aircraft.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (LIMIT 100 WORDS)
Potential non-NASA commercial applications include building structural components, armor applications, automotive and land vehicle components and structures, shipboard structures, sporting goods, and biomedical implants. Essentially, a practically limitless list of potential applications could be made if large-sized SMA components can be manufactured affordably.
