Abstract

The results of an experimental study of thermal expansion of the polycrystalline nickel NP2 brand in the temperature range 293.15–1400 K are presented. An anomaly of the linear thermal expansion coefficient in the temperature region of 500–700 K are observed. The effect of the purity of the metal on the temperature of the phase transition of the second kind is confirmed. The temperature dependences of volumetric properties of nickel NP2 brand are determined.

期刊介绍： Journal of Engineering Thermophysics is an international peer reviewed journal that publishes original articles. The journal welcomes original articles on thermophysics from all countries in the English language. The journal focuses on experimental work, theory, analysis, and computational studies for better understanding of engineering and environmental aspects of thermophysics. The editorial board encourages the authors to submit papers with emphasis on new scientific aspects in experimental and visualization techniques, mathematical models of thermophysical process, energy, and environmental applications. Journal of Engineering Thermophysics covers all subject matter related to thermophysics, including heat and mass transfer, multiphase flow, conduction, radiation, combustion, thermo-gas dynamics, rarefied gas flow, environmental protection in power engineering, and many others.
