A simple method for the calculation of the solubility limit of certain interstitial species in solid solutions from a single lattice parameter measurement is described. The calculation is based on thermodynamic considerations, and the result allows qualitative conclusions to be made about the randomness of the solute distribution. The method is used to calculate oxygen solubility limits in Nb-Zr and Nb-Hf alloys and to explain previously reported, but apparently quite different, solubility limits in the two chemically similar alloys. © 1971.
