Thermal properties of metals alloy by electrical pyroelectric method (EPE)

In present work, we propose a new technique based on uniform electrical heating of pyroelectric detector which investigated simultaneous thermal conductivity and diffusivity of samples. A new one-dimensional theoretical model was developed to determinate thermal proprieties of steel alloy. The obtained values of thermal conductivity are 13 Wm−1K−1, 18 Wm−1K−1 and 24 Wm−1K−1 and of thermal diffusivity are 7×10−6 m2s−1, 15×10−6 m2s−1 and 8×10−6 m2s−1 respectively for sheet steel, galvanized steel and stainless steel. These results are given with an uncertainty at the 1σ level.
