Temperature Dependences of the Viscosity of Metals
Abstract
For pure metals three types of given dependences are observed: (1) the polytherm has its convex side facing the abscissa, which is probably explained by the weakening of bonds during the thermal expansion of a fluid: (2) the curve has its concave side to the abscissa, the activation energy increases with a rise in temperature, which can be caused by an increase in the coordination number, the integral bond energy increases, regardless of the possible weakening of a single bond, this can also take place in the case of intensive metallization of primarily covalent bonds; (3) the given linear dependence, the invariability of E with a rise in temperature is probably explained by the compensating effect of several factors.
