Description of the Related Art Even if a certain degree of deformation is applied after cooling to a low temperature martensite phase while maintaining the shape of a high temperature austenite phase, when the high temperature austenite phase is heated, the shape returns to the original high temperature. The property of returning is called the shape memory effect. TiNi alloy has such a shape memory effect. In the case of normal processing, only the shape of the high temperature austenite phase is memorized and the shape of the martensite phase is not memorized. That is, there is no change in shape when cooled.
This is called the one-way shape memory effect. However,
By special treatment, the shape in the low temperature martensite phase can be memorized. That is, the shape of high temperature and low temperature can be repeatedly and reversibly changed only by changing the temperature. This is called the two-way shape memory effect. Treatment methods that create the bidirectional memory effect include strong working, restraint heating, training, and restraint aging. Normally, one-way shape memory alloys are combined with other parts to give a two-way shape memory effect and are used as actuators, etc. However, since the phenomenon of repeated operation of a single alloy is convenient, research and development is vigorous. However, the conventional method requires complicated processing to obtain the two-way shape memory effect.
