The interaction of matrix dislocations with twin boundaries in hexagonal close-packed metals was considered as a possible mechanism for twin growth. The crystallographic analysis of interfacial defects was carried out in terms of the dichromatic patterns which were associated with each twin. The structures and behaviors of the interface were studied by means of computer simulation. This led to the identification of a new source of twinning dislocations.
