Relative Partial Molar Gibbs Energy of Magnesium Component Substituted into Zinc Site in the Mg-Zn Binary Compounds

Abstract

Relative partial molar Gibbs energies of the Mg component substituted into the Zn site, Á " G G ). When the symmetric atomic configuration at the stoichiometric composition was violated by antisite substitution, the relative partial molar thermodynamic value of lattice defect was found to be very large.

Combinatorial Studies into the Effect of Thermally Inter-Diffused Magnesium on the Kinetics of Organic Coating Cathodic Delamination from Zinc Galvanized Steel

“…However, it has been proposed that ZM intermetallic compounds may exhibit some degree of variable stoichiometry. 28 The observed variation in Volta potential ( Y D ) values, with original Mg film thickness in Fig. 6a is most readily explained on the basis of a contact potential developing between the HDG zinc substrate and superposed MgZn IM layer(s).…”

Standard Gibbs Energies of Formation of the Ferro- and Paramagnetic Phases of AlNd3

“…However, the standard Gibbs energies of formation, Δ f G T ° , and M of AlNd 3 have not yet been investigated. In our present study, the standard enthalpy of formation, Δ f H m,298 ° , of AlNd 3 at 298 K was determined by acid solution calorimetry in a similar way to the Mg–Zn compounds − and AlNd 2 in our previous studies. The standard entropy of formation at 298 K, Δ f S m,298 ° , of AlNd 3 was determined by measuring the heat capacity, C p ,m ° , in a temperature range from 2 to 300 K by a recently developed relaxation method. − Furthermore, the standard Gibbs energy of formation as a function of temperature was obtained from C p ,m ° and Δ f H m,298 ° .…”
