Direct measurements by transmission electron microscopy on extended dislocation nodes in alloys of tin in silver have led to values for the intrinsic stacking fault energy. The values decreased smoothly from 23mJ/m2 for pure silver to 4.5mJ/m2 for 7.8at% tin, near the face-centered cubic phase limit. The results were compared with previous determinations in other silver-base alloys, and sources of systematic error were discussed. A comparison of different theoretical analyses was included.
