Abstract
NiTi samples with a density of 6.65 g/cm3 were prepared by forced SHS compaction from Ni + Ti powder mixture in an equiatomic ratio. Synthesized alloy was studied by scanning electron microscopy and X-ray diffraction analysis. It was shown that SHS-compacted sample contain NiTi (B2 + R) in addition to secondary phases: Ti2Ni, Ni4Ti3, and Ni. Electrical resistivity as a function of temperature in the range of 290–1150 K was studied.
期刊介绍：
International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
