(iv) The classical electron phonon model of resistivity, for example., the Bloch Gruneisen (BG) model retraces the reported metallic resistivity behaviour in the temperature range [T < T MI ≅ 269 (275) K]. (v) The quadratic temperature (T 2) dependence of ρ diff.
The present work deals with the study of crystal structure of new mixed cobaltite-chromite HoCo0.5Cr0.5O3 and its thermal behaviour in the temperature range of 300 1140 K by using high-resolution X-ray synchrotron powder diffraction technique.
The temperature dependence of the mean correlation time shows an Arrhenius behaviour in the temperature range from 223 to 383 K.
Open circuit voltage of the battery after charging showed slight dependence on temperature (dV/dT=0.0005), and the battery showed good charging discharging behaviour in a temperature range of 5 50°C.
The coatings studied show large differences in how their hardness, modulus and H/E vary with increasing temperature which have a significant influence on their behaviour in high temperature mechanical contact applications which have differing requirements in terms of hot hardness and plasticity.
The results show that the P-CFRP has linear behaviour in each temperature condition for both test types and that the tensile properties including the tensile strength and modulus are generally reduced as the applied temperature increases from 20 °C to 700 °C.
The thermal influence on the bistable behaviour in a local temperature field is also studied in detail.
The seasonal cycle of the 8-h ES amplitudes at 90 km (Figure 5, left panel) is quite different from the TDT behaviour in temperature (Pancheva et al. 2013, their Figure four; Yue et al. 2013), primary due to the 8-h ES maximum near 25° S.
Additionally, we have observed two distinctive issues related to magneto-volume anomalies: (i) the pressure dependence of the cell volume at room temperature shows the existence of a critical pressure at which the compound is no longer ferrimagnetic; and (ii) the cell volume shows invar-like behaviour in a wide temperature range (2 290 K), with a minimum at T ≈ 380 K.
Fire resistance and protection of cellular beams has been very controversial concerning their behaviour in elevated temperatures, the fire protection material and the required thickness.
