Abstract

Electrical resistivity of stainless steel AISI 316 L was measured by millisecond pulse-heating in the temperature range from room temperature to the melting point at approximately 1400°C. The measurement results of electrical resistivity as a function of specific enthalpy were combined with results of specific heat capacity measurements by differential-scanning calorimetry to obtain the relation between resistivity and temperature. Additionally to electrical resistivity and specific heat capacity, thermal diffusivity, density at room temperature, and thermal expansion were measured. From these results, thermal conductivity was calculated. Using the results of thermal conductivity and electrical resistivity, a Smith-Palmer-plot was drawn. It shows a significant deviation from the Wiedemann-Franz law with the Sommerfeld value due to the lattice component, electron scattering by solute atoms, and other smaller contributions.
