Simultaneous Measurements of Specific Heat, Electrical Resistivity, and Hemispherical Total Emittance by a Pulse Heating Technique: Hafnium-3 (Wt. %) Zirconium, 1500 to 2400 K.
Simultaneous measurements of specific heat, electrical resistivity and hemispherical total emittance of hafnium containing 3.12 weight percent zirconium in the temperature range 1500 to 2400 K by a subsecond duration, pulse heating technique are described. The measurements indicate decreases in specific heat (by about 13%) and in electrical resistivity (by about 8%) as the result of the α → β transformation. Estimated inaccuracies of the measured properties are: 3 percent for specific heat, 1 percent for electrical resistivity and 5 percent for hemispherical total emittance.
