Abstract

An approach to describing the thermal radiation of solid alloys, using the Ni–Cr system as an example, is proposed employing normalized entropy S/R. The emissivity is calculated using the Foote approximation based on data for the resistivity in the temperature range 400–1400 K. The provided heat flux values are normalized by density and a scale parameter \(q_{1}^{*}\) . A universal exponential dependence between the logarithm of the normalized flux and the S/R value has been established, which is applicable for all considered Cr concentrations in the alloy. The high degree of correspondence (R2 = 0.997) confirms the effectiveness of the entropy-based generalization and suggests its utility for estimating the radiative properties of alloys in the absence of direct experimental data.
