Abstract: If a shape-memory alloy (SMA) thin strip is applied to the elements subjected to torsion, a rotary driving element with a simple mechanism can be developed. In order to develop the rotary driving elements with SMA thin strip, the torsion test, the recovery torque test and the torsional fatigue test were carried out for TiNi SMA thin strip. The basic characteristics for torsion of SMA thin strip were obtained. Torque increases in proportion to torsional angle and temperature. Recovery torque increases in proportion to torsional angle and temperature. Fatigue life decreases in proportion to torsional angle. The fatigue life of the heat-treated material is longer than that of the as-received material. The fatigue limit of torsional angle of the heat-treated material is almost the same as that of the as-received material.
