Abstract
An experimental study of the heat transfer coefficients of Mg–Ca eutectic alloys with a calcium content of 10.5 and 73.0 at % is carried out. These alloys are considered as promising biodegradable and ultralight construction materials. In the course of the study, new reliable experimental data on thermal conductivity (\(\lambda\)) and thermal diffusivity (\(a\)) are obtained in the temperature range 300–\(571\ldots 695\) K of the solid state. The estimated errors of the obtained data are 3.0–3.4% and 2.0–2.4% for \(\lambda\) and \(a\), respectively. Reference tables and recommended temperature dependences of the studied properties are developed, which can be used for various scientific and practical applications.
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.
