  1. Shape Memory Alloys: NiTiNOL Wire SEEMS Team L JordyLemus Cesar Sanchez Lopez Dywanne Smith PorshaKerney

  2. Background • First record of shape memory transformation was found in 1932(AuCd) • Shape memory effect was discovered in Nickel-Titanium at the Naval Ordnance Laboratory(NiTiNOL) • Super elasticity

  3. Atomic Structure Austenite Martensite

  4. Objectives • Experiment with NiTiNOL wire to observe it’s behavior • Learn how to train NiTiNOL wire • Measure properties and examine microstructure • Design and build devices using NiTiNOL

  5. Training SMAs • Designed and shaped our NiTiNOL wire • 500° C for 15 min • Quenched in water immediately

  6. Polishing Polish the NiTinol Etched our samples Observed under two different Microscopes Experimented with NiTinol springs, rods, and tubes Used all of the preparation to build a device.

  7. SMAs revolutionized life Bone Anchors Robotic arms http://www.youtube.com/watch?v=3Srimon14CY&feature=related Medical Stents

  8. Microstructures

  9. Arrangement Maximizes the Work of the SMA
