The Avrami kinetics of dynamic recrystallization
Acta Materialia, 2009Twenty-six flow curves determined under dynamic recrystallization (DRX) conditions on 11 different steels were analyzed. The double-differentiation method was used to define the critical strain ec for initiation of DRX. The “athermal” hardening parameter h and the dynamic recovery parameter r were evaluated from the work-hardening behavior prior to ec.

Dynamic recrystallization in Al–7Mg alloy
Metal Science, 1983AbstractThe microstructural changes which occur during the extrusion of an Al–7Mg alloy have been investigated using optical and electron microscopy. Light microscopy has shown that recrystallized grains are present both at the original grain boundaries and within the grains, even at the breakthrough pressure. Electron microscopy has shown that a large

Dynamic recrystallization in high purity aluminum
Scripta Materialia, 1997It is commonly believed, that Al doesn`t undergo dynamic recrystallization (DRX), although DRX has been proven to occur in all other investigated pure f.c.c. metals. The generally accepted explanation for the nonoccurrence of DRX in Al is that due to the high stacking fault energy in Al a stable dislocation arrangement is established by extensive ...

It is well-known that strain-induced grain growth is a characteristic feature of superplastic deformation (SPD) of various materials. Such grain growth has been observed over the whole investigated interval of strains in quasi-single phase superplastic aluminum alloys 7475, Neopral and 5083.

Dynamic recrystallization under changing loading conditions
Materials Science and Engineering, 1987Abstract The occurrence of dynamic recrystallization was investigated under changing deformation conditions, including changes of strain rate and strain path and the effect of annealing. It was found that dynamic recrystallization can be delayed by predeformation at a higher strain rate or facilitated by intermediate annealing, load cycling or strain
