Heat transfer coefficients of Inconel 617 alloy

The presented research investigated the thermal diffusivity (a) and the thermal conductivity (λ) of one of the most promising heat-resistant nickel alloys, Inconel 617. The measurements were carried out in the temperature range from 300 to 1475 K using the laser flash method on the LFA-427 setup. The estimated errors of the obtained data depending on temperature were 2–4 % and 3–5 % for a and λ, respectively. A comparison with the known literature data was made. The fitting equations for the temperature dependences of the studied properties have been obtained and a table of reference values has been compiled, which can be used in various engineering and scientific tasks.
