Abstract:
The relationship of average interatomic distances to composition in single-phase alloys is discussed in terms of a simplified equation. Sample calculations on existing data show that, within the precision of most composition and lattice parameter data, the probability of an i-j pair can be considered to be those of a random arrangement of atoms and the spacing of an ij pair for alloys of n components can be considered constant over a single phase field. Although this oversimplified picture is at variance with the physical situation as inferred from diffuse x-ray scattering measurements of short-range order and from thermodynamic data, it is felt that an equation of the form presented represents a more generally useful and precise relationship between lattice parameters and compositions of alloys than the generally used linear form of Vegards Law.
