Abstract
A method for manufacturing complex shape memory alloy materials is described. The method comprises generating a particulate form of a shape memory alloy, combining the particulate with a binder, molding, heating (which may include the steps of debinding and sintering), and thermo-mechanical processing. The method allows for the formation of complex shape memory alloy materials that exhibit the desirable properties of shape memory alloys, namely shape memory and superelasticity.
