The results of an experimental study of the temperature and strain-rate dependence of Cu–Zn alloys were interpreted in terms of Seeger's theoretical analysis. The values of the stacking-fault energy, derived in this way, were compared with estimates for the same alloys; obtained directly from electron microscope observations of dislocation nodes. The lower limits for pure Cu and Ag, from the electron microscopic data, were 60 and 20mJ/m2.
