Abstract

The elemental composition, the mechanical and thermomechanical characteristics of specimens cut from different zones of cast and pressed bars are determined for assessing the possibility of commercial application of shape memory alloys of the Ti – Ni – Nb system. Statistical analysis of the results is performed using the STADIA 7.0 software. The effect of inhomogeneity of the composition of the alloy in different zones of the bars on nonuniformity of mechanical and thermomechanical properties is determined in the initial condition and after vacuum annealing. The results obtained are used in design and development of technologies for objects of the nuclear power industry.
