Abstract
Embodiments of the present disclosure provide improved techniques for creating SMA materials and SMA powders. SMA materials and powders formed may be used to form porous structures suitable for applications such as biomaterials, damping applications, actuators, and/or sensors. Embodiments for performing hydriding and dehydriding of SMA wires at low pressure and low temperature are provided. Methods may be used to produce a shape memory alloy (SMA) powder. Such methods may include hydriding a length SMA wire under low pressure for a period of time to produce a length of hydrided SMA wire, crushing the length of hydrided SMA wire to form a hydrided SMA powder, and dehydriding the hydrided SMA powder to form a dehydrided SMA powder.
Claims12
A method for producing shape memory alloy (SMA) powder comprising:
- hydriding a length SMA wire for a period of time to produce a length of hydrided SMA wire, wherein the hydriding is performed at low pressure;
- crushing the length of hydrided SMA wire to form a hydrided SMA powder;
- and
- dehydriding the hydrided SMA powder to form a dehydrided SMA powder.
