Nickel-Titanium-Based Superelastic High-Temperature Shape Memory Alloys

摘要

Shape memory alloys containing Ni, Ti, and Pt or Pd display superelastic behavior. The superelasticity was shown in a range of temperatures around the austenite finish shape memory transformation temperature. The superelasticity range was approximately 210-280° C. for these alloys. Shape memory alloys that exhibit superelasticity at high temperatures will enable a new class of mechanical sensors and actuators.
