THE STACKING-FAULT ENERGY IN α-SILVER – TIN ALLOYS

Abstract
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 23 erg/cm2 for pure silver to 4.2 erg/cm2 for 7.8 at.% tin. The results are compared with previous determinations in other silver-base alloys.
