Processing Smart Wires from Cu-Al-Ni System
Abstract
In this paper we present some results concerning plastic deformation applied
to shape memory alloy and two most direct characterization methods for shape
memory. We work with a copper based alloy- Cu Al13Ni 4. Over eight percent in
aluminum the plastic deformation on the copper aluminum alloys is very difficult to
do. Our purpose was to obtain the thin wires. The first material shape was cast
ingots very fragile. We choose to work with a direct extrusion method because the
high fragility of this material required a three dimensional stress compression
scheme.
