Figure 1 shows an embodiment of this invention.
Figures A and B relate to a pipe joint with a female seat. Figures A and B show a state in which the pipe joint changes from state A before joining to a female seat rod with the tube tip expanded in diameter by heat treatment. Figures A and B are modified examples. This is a diagram showing a state in which a pipe in a straight cylindrical state (outer diameter: φD2) before joining is transformed into a male sheet with the pipe tip tapered in diameter (outer diameter: φD3) by heat treatment,
Figure 3 shows general stress-strain lines for shape memory alloys, Figure 4 shows stress-strain lines for Ti-Ni alloy (nitinol), and Table 1 shows stress-strain lines for several types of shape memory alloys. Table showing M s points and A s points, 2nd
The table shows several types of shape memory synthetic resin materials, the internal mechanism of shape fixation in primary and secondary molding, shape memory temperature, and shape recovery temperature. Figures 5 and 6 are diagrams showing conventional examples. . 5, 8...pipe (tube), 6, 9...nut (
