NASA Glenn develops high-temperature Ni-Ti-Pt shape memory alloy for actuators
NASA Glenn Research Center, Cleveland, Ohio, has developed a range of compositions and a method to produce nickel-titanium-platinum (Ni-Ti-Pt) high-temperature, high-force shape memory alloys. These alloys and their processing method have been demonstrated in fine rod and wire, and in demonstration components. Ideas and collaborations are sought for actuation devices in various space structures, for changing the shape of structures on demand.
Shape memory alloys can simplify actuation devices and reduce the weight of space structures. In addition, shape memory alloys can be used to create morphing structures by changing the shape of components on demand without the need for heavy hydraulic mechanisms.
