| Abstract |
An review of the temperature dependences of the elasticity characteristics of cubic crystals of simple substances is presented. It is shown that the general trend is a decrease in elastic moduli E, G, and B with temperature due to the weakening of interatomic bonds caused by thermal expansion of the crystal lattice. However, there are also anomalous dependencies, such as an increase in the shear modulus G with temperature, observed for BCC crystals of vanadium V, niobium Nb, tantalum Ta, and FCC crystals of palladium Pd, platinum Pt. A common feature for the cubic crystals considered, except for BCC chromium Cr, is an increase in Poisson’s ratio ν with temperature. The factor of elastic anisotropy A also shows a general upward trend, but for some crystals, BCC V, Nb, Ta, and FCC Al, local minima are observed, and for BCC Cr and FCC Pd, maxima are observed. |
