Twinning is an important mode of deformation in magnesium and its alloys. Twins also play
an important role in the fracture of the alloys, by stress concentration of dislocations on the
twin boundaries of the common {10-12} type twins, or formation of {10-11}-{10-12}
double twins. Dislocations also play important role in nucleation and growth of twins.
Nucleation of twins and double twins, mainly {10-12} type, has been subject of a number of
studies, experimental as well as computational. In this study, nucleation of {10-11} type
twins has also been studied.
