Strength of Dislocation Junctions in FCC-monocrystals with a \( \left[\overline{1}11\right] \) Deformation Axis

Abstract

The paper examines all dislocation reactions implemented in FCC-monocrystals with axis deformation oriented in the \( \left[\overline{1}11\right] \) direction. It identifies the fracture stresses of dislocation junctions depending on intersection geometry of the reacting dislocation loop segments. Estimates are produced for the full spectrum of reacting forest dislocations. The paper presents the statistical data of the research performed and identifies the share of long strong dislocation junctions capable of limiting the zone of dislocation shift.
