Young's Moduli of Pure Metals - Review of Some Relations at Various Temperatures
Alfred Buch
ABSTRACT In many cases for metals belonging to the same subgroup (e.g. Mo and W) the increase of temperature below 0.5 melting point results in a very weak change of the difference E''- E' for the two metals. At room temperature the ratios E'/E'' have in many cases close values to corresponding ratios of the specific heat capacities and of the latent fusion heats in energy concentration units. The ratio of the fusion heat L to the specific heat capacity W at 0°K is often quite similar for two metals belonging to the same subgroup. The periodic magnitude sequence of Young's moduli at temperature 4.2°K, in the case of continuous rise of atomic number (AN), is identical to the magnitude sequence at 293°K and to the magnitude sequence of the latent fusion heat. In the case of lanthanide metals (AN=58 to 68) the magnitude of E-moduli increases with AN rise, similar to the magnitudes of the melting point, specific heat capacity, latent fusion heat and density, with three exceptions (Eu,Yb,Lu).
