On the basis of the theory of dimensions, the relationship between the periodicity of the Debye temperatures of metals and integral hemispherical fluxes of thermal radiation is revealed. The periodicity of the Debye temperatures of metals is established in accordance with the position in the Periodic...
The validity of Hill's formulas for the shear modulus of a polycrystalline cubic solid is examined by calculating the Debye characteristic temperature at 0 掳K for a number of cubic metals using the measured elastic constants. The results are compared with calorimetric values and the numbers ...

where Θs can be defined similarly as in (2.10) and termed as the surface Debye temperature. The examples of measured root-mean-square (rms) amplitudes of surface atoms and the corresponding surface Debye temperatures at the (111) face of some fcc metals are given in Table 2.3. Table 2.3...
The Debye temperature can be obtained from X-ray intensities also but such work on the rare earth metals is conspicuously meagre. We report here the results of our investigation on ytterbium which is face centered cubic at room temperature. Experimental The ytterbium metal used in this study was...
Temperature dependence of the anharmonic Debye-Waller factor for some cubic metals are calculated by employing our recent dynamical model. Willis anharmonic approach has been followed to estimate the effect of anharmonic terms in the crystal potential. A comparative study of the computed values and ...
A new method of analysis of the specific heat data of ferromagnetic metals is applied to nickel. This method utilizes in a direct manner experimental results of the temperature-dependent saturation magnetization and thereby yields a more realistic estimate of the magnetic specific heat contribution than...
that as the hydrogen content increases,the Debye temperature decreases,but the lattice parameter of the aUoy increases.The above results experimentally support the decohesion theory that the in- crease of hydrogen in metals will weaken the cohesive force between the atoms and make met- als brittle...
