  • Despite similarities in crystallography and electronic structure in titanium and zirconium, it is shown that plasticity proceeds differently between the two, associated with differing dislocation configuration stability.

  • Work hardening of tungsten in the thermally activated regime is highly orientation dependent. Here, we show that kink-pair nucleation controlled coupled motion of repulsively oriented screw dislocation pairs occurs and leads to an orientation dependent additional plastic slip on unexpected slip systems.

  • Observations by transmission electron microscopy of deforming niobium and tungsten at low temperature shows that anomalous slip in body-centred cubic metals arises from the unusually high mobility of multi-junctions, which is a source of softening.
