Popis: 1. Shape-memory alloy Ti - 45% Ni - 10% Nb with a wide hysteresis of the martensitic transformation can be used for thermomechanical coupling of pipelines. Disassembled thermomechanical clutches can be stored at room temperature and assembled with heating to a temperature somewhat exceedingt room; the joint can be easily disassembled by RSME under deep cooling. 2. Treatment of alloy Ti - 45% Ni - 10% Nb by the recommended method provides the following characteristics of shape recovery: a reversible deformation of high-temperature SME of up to 8%, a degree of shape recovery of up to 60–80%, a temperature range of shape recovery from + 30 to + 90°C, and a reversible deformation of the RSME of 1–2%. 3. The deformation that induces the SME in the considered alloy can be performed from −10 to −70°C at e=10–12%; the thermomechanical clutches can be stored at a temperature of up to +30°C; the parts can be coupled with the help of a thermomechanical clutch in a temperature range from +30 to +100°C. The coupling is easily detachable after deep cooling due to the realization of the reversible SME.
