Fig. 4: Deformation behaviour of tungsten single crystals for the [100] and [111] loading direction.
From: Repulsion leads to coupled dislocation motion and extended work hardening in bcc metals
The experimental curves are taken from Beardmore and Hull14. For the [100] direction an extended work-hardening regime is observed; crystal plasticity simulation results without (CP(std)) and including the coupling mechanism (CP (coup)) are shown for both orientations. (A detailed comparison is included in Supplementary Discussion). The coupling mechanism leads to an extended work hardening regime for [100] representing well the experimental findings, while for the [111] orientation the deformation behaviour is only slightly changed.
