| Description | Journal: Journal of Physics F: Metal Physics Computes the electronic contribution to the energy of formation of vacancies in disordered transitional alloys in a tight-binding model. The authors show that this contribution is smaller than the value obtained from a linear interpolation between the values of the alloy constituents. This behaviour is compared with that of the cohesive energy which is known to be often larger in the alloy than the value obtained in the ideal solution approximation (i.e. the energy of formation of the alloy is negative). These two quantities have the same value in a pair approximation and the difference in their behaviour is therefore due to band structure effects, the cohesive energy being related to the average properties of the system while the energy of formation of a vacancy is related to the range of a perturbation of the system. |
