The authors have already shown that the rate of solid solution hardening in binary Ni-X alloys for such solute X as having solid solubility was larger than that as making continuous solid solutions for the same atomic size misfit parameter. Also it has been shown that the degree of solid solution hardening could be correlated with the extent of solid solubility of a solute X. In the present work, further evidence for such correlation is sought after by literature survey on Cu-X and Au-X alloys and by an investigation on the solid solution hardening in Ni-Au and Ni-Pd alloys. It is shown that the former is true for at least in Cu-X alloys and the latter is so in all the binary systems examined. The reason to provide extra hardening for a solute with limited solubility to the solvent is relevant in nature to some properties which increase with increasing size misfit parameter and are well correlated with atomic interaction parameter between a solute and a solvent atoms.
