摘要:

The nature of ‘grown-in’ dislocations formed in melt spun ribbons of the compound Nb3Al have been studied using transmission electron microscopy. These dislocations have b = ⟨100⟩ and are predominantly screw in character. They are dissociated into two partial dislocations which bound a complex stacking fault according to the reaction
