“…The fact that relatively small amounts of Si are able to stabilize the cubic LaFe,, phase in the La-Fe systems shows that the heat of alloying is only slightly positive in the Fe-rich portion of the La-Fe system, which agrees with model predictions [16].…”

The magnetic properties of the cubic NaZn,, type pseudobinary compounds La(T,Si, _X),s were studied for T = Fe, Co and Ni in the temperature range 4.2-300 K. 57Fe Mossbauer spectroscopy was performed on LaFe,,Sia and "Fe-doped LaCo,,Si,.The compounds with T = Fe or Co are ferromagnetic, while the compound LaNi,,Si, is a Pauli paramagnet. The critical behaviour around the Curie temperature T, was studied in La(Fe,Si, _X)13 by measuring the temperature dependences of the zero-field susceptibility and the electrical resistivity. The critical exponent y in the expression x a (T -TC)-y was found to be close to 1.38 corresponding to an isotropic Heisenberg ferromagnet. The anomalous critical behaviour shown by electrical resistivity can be explained in terms of lattice softening associated with the Invar effect.

“…THE semiempirical formation enthalpy model for binary alloys suggested by Miedema and co-workers [1,2,3] in the early 1970s has been developed into a successful one which includes only three parameters: electronic density, atomic volume, and electronegativity. Based on a large number of experimental data, a formation enthalpy calculation formula for binary systems which contain almost all possible binary systems has been established.…”

In this paper, copper-5 wt.%-tin (Cu-5wt%Sn) powder mixture was mechanically alloyed in order to study the solid solubility extension during the alloying process. Nanocrystalline supersaturated solid solution has been prepared in this system by high energy ball milling. Based on the thermodynamic model, the Gibbs free energy change in this alloy system during the formation of solid solution is calculated to be positive, which means that there is no driving force to form solid solution in coppertin (CuÀSn) immiscible system. It has been found that a large fraction of grain boundaries and a high density of dislocations play a significant role in the solid solubility extension of immiscible copper and tin.
