High-temperature thermal conductivity of zirconium-based alloys

Thermodynamic evaluation of pure Co for the third generation of thermodynamic databases

“…The value of β was obtained by fitting to the heat‐capacity data from Refs. and between 1350 and 1400 K. Finally, the metastable bcc phase was assessed. Other thermodynamic quantities were derived from the description of the heat capacity.…”

“…Different values have been reported using different experimental methods to determine T c of fcc Co. Generally, the value of T c obtained from the magnetization measurements is 20 K higher than the value obtained by calorimetry . This discrepancy was partly resolved by the work of Peletskii and Zaretskii . They investigated the thermal properties of Co near the Curie point using a plane‐temperature‐wave technique.…”

“…In our work, we treated the Einstein temperature as a fitting parameter using an initial start value derived from the Debye temperature reported by Ref. and applying the relation θ E = 0.714 θ D (0) .…”

“…Apart from the work we reviewed in Section 3.1 [22][23][24][25], thermochemical information for fcc was also presented by Jaeger et al [33], Wuest et al [34], Umino [35], Peletskii and Zaretskii [36]. Fcc Co is also ferromagnetic.…”

A new high pressure and temperature equation of state of fcc cobalt

“…6,7 At ambient pressure, there have been several studies on its thermal expansion [8][9][10][11][12][13][14][15] and heat capacity. [16][17][18][19][20][21] High-pressure measurements of cobalt's compressibility have been made by Antonangeli et al, 1 Yoo et al, 5 and Fujihisa and Takemura. 22 Here, we measure the high pressure and temperature bulk thermoelastic properties of fcc cobalt metal, explicitly taking the magnetic transition into account in the formulation of the Mie-Gr€ uneisen-Debye equation of state.…”
