Additively manufactured wire products formed from nickel-titanium shape memory alloys

Abstract

A method of producing a wire product from a nickel-titanium shape memory alloy, and a wire product produced by such method. The method includes consolidating a nickel-titanium shape memory alloy to a preform using an additive manufacturing process. Thereafter, the preform may be subject to a hot working process, including heating the preform and deforming the preform, such as by, forging, extrusion, rolling, swaging, and the like. The hot-worked preform may be annealed following hot working. The preform may then be subjected to one or more cold working processes including drawing, swaging, rolling, and the like. Annealing may also occur after cold working. The hot and cold working processes may impart significant diameter reduction to form the wire product.
