Dynamic Recrystallization in Zirconium Alloys [PDF]
Journal of ASTM International, 2010 In 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.

Modeling the process of dynamic recrystallization [PDF]
Metal Science and Heat Treatment, 1997 A structural approach to modeling dynamic recrystallization is suggested. A model of nucleation and growth of recrystallized grains is considered with allowance for the special features of determination of the energy constants of the process of recrystallization. A relationship between the grain diameter, which is a very important structural parameter,

Using Grain Boundary Irregularity to Quantify Dynamic Recrystallization in Ice
Acta Materialia, 2021Dynamic recrystallization is an important mechanical weakening mechanism during the deformation of ice, yet we currently lack robust quantitative tools for identifying recrystallized grains in the “migration” recrystallization regime that dominates ice ...

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 kinetics
Metal Science, 1979AbstractDynamic recrystallization in two austenitic stainless steels has been monitored by (i) observations of the high-temperature stress/strain behaviour, and (ii) metallographic measurements on rapidly quenched, partially reacted specimens. Particular effort has been put into assessing the influence of pre-existing grain size on the kinetics of ...

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: 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 ...
