shape memory

   Also found in: Wikipedia 0.01 sec.
shape memory, property possessed by certain alloys alloy [O. Fr.,=combine], substance with metallic properties that consists of a metal fused with one or more metals or nonmetals. Alloys may be a homogeneous solid solution, a heterogeneous mixture of tiny crystals, a true chemical compound, or a mixture of these.

This effect results because, as the alloy is deformed, it undergoes a martensitic (or athermal) transformation—a solid-state transition that rapidly changes the crystalline structure of the alloy without thermal activation—that is readily reversed once an appropriate amount of heat is applied. Among the alloys are copper-aluminum-nickel, copper-zinc-aluminum, nickel-titanium, and iron-manganese-silicon. Applications of shape memory include heat-activated fasteners, switches, eyeglass frames, orthopedic devices, teeth braces, and blood clot filters.

The magnitude of electrical conductivity of the composites and the possibility of shape memory actuation by resistive heating remained unexplored, especially in light of low shear dispersion in chaotic mixer and anticipated reduction of PCL-diol crystallinity in the presence of CNF and ox-CNF.
