从测量的曲率半径的延伸位错节点观察到的透射电子显微镜，堆垛层错能已被确定为一些铜和银基铝和锌固溶体合金，也为一些镍钴合金。铜、银和镍的层错能粗略估计分别为40、25和150 erg cm-2。测量的准确性和溶质原子偏析的堆垛层错的可能性进行了讨论。
From measurements of the radius of curvature of extended dislocation nodes observed by transmission electron microscopy, stacking-fault energies have been determined for a number of copper and silver base aluminium and zinc solid solution alloys and also for a number of nickel-cobalt alloys. Rough estimates of about 40, 25 and 150 erg cm−2respectively can be made of the stacking-fault energies of copper, silver and nickel. The accuracy of the measurement and the possibility of segregation of solute atoms to stacking faults are discussed.
