Single crystals of copper and nickel were plastically deformed at room temperature into
stage III of the work hardening curve and by creep at 0.4 T m (melting temperature). The …

Tapered copper single crystals oriented for single slip are deformed plastically at room
temperature and at 77 K. TEM investigations at resolved shear stress levels of 20, 30, and …

Previous studies on the strain rate sensitivity of the stress for copper single crystals and
polycrystals generally agree in defining a limiting value~= 103 s 1 between the static and the …

Transmission electron microscopy (TEM) observations of the dislocation substructure
developed in high-purity single crystals of Cu deformed at 4.2 K have been carried out in …

An electron microscopic investigation is described of the effect of high temperature
annealing on deformed copper single crystals containing dispersed second phases of either …

The deformation structure of [189] oriented copper single crystals was investigated at
incipient dynamic recrystallization for different deformation temperatures (T> 0.5 T m and …

It is proposed that, during dislocation glide at low temperatures, both screw and non-screw
dislocations annihilate mutually with dislocations of opposite sign approaching on closely …

The static recovery behaviour of copper and nickel single crystals deformed in multiple slip
was investigated in mechanical tests and in HVEM in situ annealing experiments. Recovery …

The formation of point defects during plastic deformation and their subsequent interactions
with dislocations in high‐purity copper was studied using a low‐temperature strain‐aging …

The variation of the total “active dislocation length”, defined as the product of the density of
mobile dislocations and the active slip volume, is determined during changes of deformation …
