Scope Shape memory alloys (SMAs) have potential to be designed or integrated into multifunctional systems for energy transfer in addition to actuation, morphing, and sensory capabilities in industries including automotive, aerospace, robotics, and biomedical devices across multiple length scales. The 2007 US market revenue of these alloys in medical devices was $1.4 billion. The desired properties can be achieved by developing the required microstructure via processing.

NiTi and other shape memory alloys respond to variation in applied stress and temperature by significantly changing their mechanical behavior. Due to their unique mechanical properties, traditional machining processes are extremely difficult and, in some cases, impossible. Additive manufacturing (AM also known as 3D printing) provides an attractive alternative for near net shape fabrication of these alloys.

This symposium seeks fundamental as well as application related papers based on these materials. Areas of interest include

- modeling to predict the functional properties of the resulting alloys
- fabrication methods
- experimental characterization
- microstructural studies
- patient specific medical devices
- energy transfer applications
- damping and disaster mitigation
