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.

NiTi的强制SHS压实

以等原子比的Ni + Ti粉末混合物为原料，采用强制SHS压实法制备了密度为6.65 g/cm3的NiTi样品。通过扫描电镜和x射线衍射分析对合成合金进行了研究。结果表明，shs压实试样除含有Ti2Ni、Ni4Ti3和Ni等次生相外，还含有NiTi (B2 + R)。研究了在290 ~ 1150 K范围内电阻率随温度的变化规律。

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.
