The article deals with the unique alloy on the basis of titanium nickelide with thermomechanical shape memory. It is spoken in detail about the alloy's memory effect phenomenology. The main reasons constraining the application of alloys with shape memory in the production technologies in different branches of technology, including constructing industry are reflected. The efficient area of possible application of that kind of alloys is shown. In this article is also proposed a method of calculation of  power elements, executed from titanium nickelide alloy, and also the examples of alloy's application in practice. It is shown that the offered technique of a preliminary temperature cycling of power elements made of titanium nickelide allows to reach the maximum possible straining and power characteristics.

Keywords: alloys with shape memory, a martensite, a temperature cycling, titanium nickelide, range of application, a calculation method, power element, straining and power characteristics.
