The study of deformation twinning has long history. However new, sometimes surprising,
findings have shown that the phenomenon of deformation twinning still is not completely understood.
During recent years, some debates are taking place in the scientific literature concerning deformation
twinning mechanisms in metals with hcp structure. These debates deal with the importance of special
twin boundary dislocations named disconnections, growth and nucleation of twins, non-Schmid
behavior of twinning, di erence of deformation produced by twins from simple shear. They invoked
new propositions for atomistic mechanisms of deformation twinning. The purpose of this review is
to compare the classical theories of interfacial defects with the new findings and prove that many of
these findings can be understood in terms of these well-established theories. The main attention is
paid to summarizing the explanations of di erent phenomena in terms of disconnection mechanisms
in order to show that there is no contradiction between these mechanisms and the new findings.
