Abstract : Determination of the stacking fault probabilities (densities) in the Ag-Li system as a function of atom fraction of Li in the alloys is reported. The Ag-Li system shows extensive solubility of Li in Ag. This system is unique since it is the only one reported which shows an alkali metal having a significant solubility in a noble metal. The fact that the solvus curve is practically independent of temperature and that the lattice parameter changes by only about 1% below the value for pure Ag indicates that the size effect is quite small; (independent evidence from diffuse scattering of X-rays also agrees with this result). The observed decrease in stacking fault energy is thus what one expects due to the large difference in the electronegativity of Ag and Li.
