A continuum based microstructure model of inhomogeneous hardening and recovery as a pre-stage of recrystallization nucleation

Abstract: Starting from the fundamental relation between the diffusion flux of point defects (vacancies, interstitials) and the gradient of the diffusion potential the diffusion equation is set up and applied to the calculation of the concentrations of both types of point defects. Thereby, all possible sources and sinks and their mutual effects are taken into consideration. These equations are coupled with the equations for the temporal derivatives of dislocation density, porosity, pore size and temperature. For the clo… Show more

“…K VD ≈1, K VP ≈1 and K F ≈1 are constants, ν L is the frequency of lattice vibrations, p P the porosity, δ P the mean pore diameter, C P =6 a constant for spherical pores, A Vc the activation energy of self diffusion, A F the formation energy of Frenkel pairs, A Vm and A Im the migration energy of a vacancy or interstitial, respectively. For the production rates of the interstitials, analogous equations exist [1].…”
