When dynamic recrystalllsatlon occurs during constant straln-rate tests, the stresswithin the sample tends to a steadyj or "saturation" value. This steady-state stress isassociated with a new, and constant mean grain size within the material. These effects arecaused by cycles of nucleatlon and recrystallisation which occur out-of-phase at numeroussites

Dynamic and Static Recrystallization
Advanced Engineering Materials, 2001Dynamic or static recrystallizations are certainly the main mechanisms responsible for the microstructure and texture changes occurring during or after deformation. New experimental devices to produce large strains (Equal Channel Angular Extrusion, ECAE) and to investigate the microstructures (orientation mapping by electron backscattering diffraction,

Dynamic Recrystallization: The Dynamic Deformation Regime
Metallurgical and Materials Transactions A, 2007Severe plastic deformation (PD), especially involving high strain rates (>103 s–1), occurs through solid-state flow, which is accommodated by dynamic recrystallization (DRX), either in a continuous or discontinuous mode. This flow can be localized in shear instability zones (or adiabatic shear bands (ASBs)) with dimensions smaller than 5 μ, or can ...

Dynamic Recrystallization in Titanium Alloys
Key Engineering Materials, 2016The results of the investigations on five different titanium alloys were presented in this paper. Two two-phase α+β alloys (Ti-6Al-4V and Ti-6Al-2Sn-4Zr-6Mo) as well as two β alloys (Ti-10V-2Fe-3Al and Ti-3Al-8V-6Cr-4Mo-4Zr) were studied. Moreover, Ti-48Al-2Cr-2Nb intermetallic alloy (γ alloy) was also investigated.

Dynamic recrystallization of zirconium carbide
Scripta Metallurgica, 1976Results of compression testing of ZrC are presented which show that in the range 1200 to 1800$sup 0$C these materials may undergo dynamic recrystallization. The predominant deformation mechanism near the yield stress is carbon diffusion-assisted motion of dislocations.

Dynamic Recrystallization in Tial Alloys
MRS Proceedings, 1992TiAl alloys with Cr, V, and Nb additions show promise as high temperature materials due to their high temperature strength and modulus. Dynamic recrystallization has been shown to be important for the processing and superplastic forming of these materials.

Dynamic Recrystallization in Zirconium Alloys
Journal of ASTM International, 2010In this investigation, the characteristics of dynamic recrystallization (DRX) in five Zr-alloys, namely, commercial pure zirconium (CP-Zr), Zircaloy-2 (Zr–Sn), Zr-2.5Nb (Zr–Nb), Zr-2.5Nb-0.5Cu (Zr–Nb-Cu), and Zr-1Nb-1Sn-0.1Fe (Zr–Nb–Sn–Fe), have been examined.

Microstructure mechanism map of dynamically recrystallized marble
Tectonophysics, 2006Abstract The relative nucleus density (RND) model of dynamically recrystallized grain size [Sakai, T., Jonas, J.J. 1984. Dynamic recrystallization: mechanical and microctructutal consideration. Acta metallurgica, 32, 198–209] was applied to experimentally and to naturally deformed marbles that have undergone dynamic recrystallization. The model shows

Development of dynamic recrystallization theory
Materials Science and Engineering: A, 2004Although hot working had been defined as deformation above the recrystallization temperature (determined after cold working), it was only about 1965 that dynamic recrystallization (DRX) was confirmed to be occurring during the deformation; two decades were required to clarify the similarities to, and the differences from, static recrystallization.
