Abstract
Dislocations in (101¯2), (112¯2) and (112¯1) twin interfaces in hexagonal-close-packed metals are investigated using computer simulation techniques. The geometrical aspects of these defects, i.e. their Burgers vectors, b, and step heights, h, are obtained using a recently developed treatment of interfacial defects which takes into account the total symmetry of the crystals. It is shown that, in addition to the twinning dislocations identified by previous treatments based on the symmetry of th...
