Heat transfer coefficients of Mg70Li30 ultralight alloy

Heat transfer coefficients of Mg70Li30 ultralight alloy The transfer properties of a congruently melting Mg-Li alloy with a lithium content of 30 at. %, considered as a promising ultralight structural material for the aerospace industry, have been studied experimentally. New experimental data on thermal diffusivity (a) and thermal conductivity (λ) have been obtained in the temperature range of 293–777 K with estimated errors of 2–4 % and 3–5 %, respectively. The results have been compared with the known literature data on thermal conductivity of Mg-Li system alloys. A table of recommended temperature dependences for a and λ of the studied composition has been developed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Thermophysics and Aeromechanics Springer Journals

Abstract

The transfer properties of a congruently melting Mg-Li alloy with a lithium content of 30 at. %, considered as a promising ultralight structural material for the aerospace industry, have been studied experimentally. New experimental data on thermal diffusivity (a) and thermal conductivity (λ) have been obtained in the temperature range of 293–777 K with estimated errors of 2–4 % and 3–5 %, respectively. The results have been compared with the known literature data on thermal conductivity of Mg-Li system alloys. A table of recommended temperature dependences for a and λ of the studied composition has been developed.
