来る。FIG. 1 is a diagram showing a bracelet-type watch band using a shape memory alloy. Figure 1 shows a structure in which a shape memory alloy watch band and a watch are made in one piece, and the watch is attached to the band. For this watch band, for example, the shape of each individual's wrist is made in advance using plaster, and the shape is made to fit the wrist of the person who uses the watch. The shape of the band was adjusted to 400℃ using a mold that matched the shape of the wrist of the person using the watch.
By heat-treating at a temperature of 30 minutes to 4 hours at a temperature of 500° C. to 500° C., a watch band having a unique shape can be obtained.

On the other hand, in order to create a stable austenite phase to ensure superelastic properties in a Ni-Ti alloy memory alloy, as mentioned above, the alloy composition ratio of Ni and Ti,
Generally, in order to obtain a stable austenite phase below 0°C, it is possible to obtain a stable austenite phase by increasing the Ni composition ratio and the heat treatment temperature, but the value of the allowable deformation that does not cause permanent deformation is If the upper limit temperature at which the superelastic properties can be stably guaranteed is 45°C, the lower limit that can be obtained with the same material is about 15°C.
