Line tension, inverse energy plots and dislocation instabilities

Line tension, inverse energy plots and dislocation instabilities

Straight glide dislocations have been shown to assume a zig-zag shape even though this results in an increase in line length. This occurrence has been attributed to a negative line tension factor. This phenomena of dislocation instabilities can be analyzed in terms of inverse energy plots. 6 ref.--G...

Zusammenfassung:Straight glide dislocations have been shown to assume a zig-zag shape even though this results in an increase in line length. This occurrence has been attributed to a negative line tension factor. This phenomena of dislocation instabilities can be analyzed in terms of inverse energy plots. 6 ref.--G.P.K.
