Viscosity, Thermal Expansion, Heat Capacity and Bend Stress Relaxation of La_(50)Al_(25)Ni_(25) Glassy Alloy Governed by Relaxation Phenomena

摘要

The temperature dependencies of the viscosity, the thermal expansion and heat capacity deviations from linear temperature dependence, as well as the bend stress relaxation kinetics of a La_(50)Al_(25)Ni_(25)glassy alloy have been determined quantitatively. It has been shown that the experimental temperature dependencies of these properties can be successfully described using the Free Volume Model. The calculation of the temperature dependencies studied has been carried out with a common set of model parameters.
