Abstract
An experimental investigation of the heat capacity of corrosion-resistant refractory nickel base alloy ChS88U-VI used as a material of the turbine blades for marine engines, blades of converted aircraft gas turbine engines and industrial gas turbine was carried out for the first time. The heat capacity of the alloy has been measured by the method of differential scanning calorimetry in the temperature range 300–1270 K of the solid state, including the phase transition region. The estimated error of the data obtained was 2–4%. The comparison with the promising nickel based superalloys Inconel 617 and Inconel 718 was made. Approximation equations and a table of recommended values of ChS88U-VI alloy heat capacity were developed for use in various engineering and scientific tasks.
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.
