Transmission electron microscopy examination and analysis of an anomalous stacking fault in h.c.p. metals

Abstract

An anomalous stacking fault is reported that is observed within deformation twins in Ti and Zr. Their formation may be restricted to situations where deformation twinning takes place. An understanding of this process sheds new light on the twinning process. In this work the crystal structure of the stacking fault and its formation mechanism are investigated.
