FIG. 1.

A HREM image of a twin formed by plastically deforming electrodeposited NC Ni. The twin was formed by the emission of partials from the grain boundary on the left and it ended in the grain interior as marked by the white asterisks.

FIG. 2.

Schematics of a square grain with a dislocation line parallel to the grain boundary. The dislocation has a Burgers vector of . The slip plane is , which is parallel to the page.

Image of FIG. 3.
FIG. 3.

The grain shape change caused by the first twinning mechanism in which all twinning partials have the same Burgers vector. The 141° grain boundary kink can be seen from an orientation perpendicular to the Burgers vector.

Image of FIG. 4.
FIG. 4.

The grain shape change caused by the second twinning mechanism in which approximately equal numbers of partials and partials are involved. The 158° grain boundary kink can be seen from an orientation perpendicular to .
