摘要：

Combined studies of the properties of the 50Ti-40Pd-10Ni alloy with a high-temperature shape memory effect have been carried out. The elemental and phase compositions and its mechanical and thermomechanical characteristics have been determined. Samples cut from the strip with a thickness of 2.04 mm have been studied. The phase transformations are in the range of M (f) = 371.3A degrees D to A (f) = 436.9A degrees D. These are acceptable values. The maximum values of the shape memory effect epsilon(SME) and of the degree of shape recovery eta(SME) are 3.9 and 49%, respectively. These values are insufficient to create workable safety devices. These characteristics can be improved via optimal changes in the elemental composition of the shape memory alloy and by an adequate choice of the regimes of heat treatment and of the regimes of providing strain in the investigated objects. The results of these studies are necessary in order to develop different devices used in nuclear power plants.
