Effect of redundant deformation on recrystallisation behaviour of copper

Influence of Recrystallization Annealing Modes on the Mechanical Properties of Copper Pipes After Large Plastic Deformation

“…A further increase in temperature results in an increase in grain size up to 40 µm. This is compliant with the laws established in metal science [10,11]. An increase in annealing time to 80 min revealed that there was a local maximum at a temperature of 600°C.…”

Enhanced recovery and recrystallization of metals due to an applied current

“…Fig 2A), indicating that no significant recrystallization has occurred during the 20 min at 300°C. This observation is consistent with previous findings that substantially higher temperatures are required to recrystallize moderately deformed CP Cu [15]. This conclusion is reinforced by the pole figure, which exhibits the same texture and strength as the deformed state.…”

Effect of strain path change on recrystallisation in copper

“…Embury et al 5 working with aluminium deformed by uniaxial compression with a change in compression axis, showed that recrystallisation kinetics correlated well with the final flow stress but not with the accumulated plastic strain. A similar conclusion was reached by Lindh et al 6 working with uniaxial tension and compression of copper. Cowan et al 7 using torsion combined with either reverse torsion or axial compression in aluminium, confirmed the profound influence of reversed straining on recrystallisation kinetics but observed almost no deviant effect of torsionzcompression (orthogonal states).…”

“…The conclusion that strain measures cannot be used, at least in any simple way, to predict recrystallisation behaviour was also reached previously. 5,6 Both those studies showed that the final flow stress gave much better correlation. The plot of T 0 .…”
