Microstructure-Mechanical Property Relationships for Ni-Ti-Pt High Temperature Shape Memory Alloys

Grant Hudish & Michael Kaufman
Within the past decade, NASA has been developing high temperature shape memory alloys (HTSMAs) for use as simple, robust, and lightweight solid-state actuators. Shape memory alloys (SMAs) as actuators are considered nonconventional and advanced actuation devices and are capable of providing a power to weight ratio greater than that of DC motors, pneumatic systems, and comparable to that of hydraulic systems, in a much more compact and simplified geometry. Alloys of Ni and Ti in...
