Measurements of Specific Heat and Electrical Resistivity of Austenitic Stainless Steel (St. 1.4970) in the Range 300-1500K by Pulse Calorimetry

A direct heating pulse calorimetric technique has been applied for the measurements of specific heat, electrical resistivity, and hemispherical total emissivity of austenitic stainless steel (St. 1.4970), a candidate for thermal conductivity standard reference material. The specific heat and electri...

Description
Summary:A direct heating pulse calorimetric technique has been applied for the measurements of specific heat, electrical resistivity, and hemispherical total emissivity of austenitic stainless steel (St. 1.4970), a candidate for thermal conductivity standard reference material. The specific heat and electrical resistivity were measured in the range 300-1500K, and the hemispherical total emissivity was measured in the range 1300-1500K. The maximum measurement uncertainties were estimated to be 3% for specific heat, 1% for electrical resistivity, and 5% for emissivity.
