Abstract

A notable two-way effect can be induced in components made of a memory alloy exhibiting only a one-way effect by applying an external force which gives rise to an internal stress opposing the one-way effect. Component made of a memory alloy in the form of a tension, compression bending, or torsion rod (helical spring 2). External force by weight or spring (counter-spring 3).
