Thermal diffusivity of La98.8Fe1.2 alloy in the temperature range of 293–1623 K
2020
The laser-pulse method was used to measure the thermal diffusivity of La98.8Fe1.2 alloy in the temperature range of 293–1623 K of the solid and liquid states, including the regions of phase transformations. The measurement uncertainties of the heat transfer coefficients were ± (3–6) %. Approximating equations and tables of reference data on thermal conductivity and thermal diffusivity of La98.8Fe1.2 alloy have been obtained for scientific and practical use. A comparison of measurement results with known literature data on thermal diffusivity of pure lanthanum has been carried out.
