Role of Recovery in the Recrystallization Simulation Application to a Cold Rolled IF-Ti Steel and a Cold Drawn Copper Wire

Abstract

A simple model including the recovery and nucleation kinetics is proposed to simulate recrystallization using a Monte Carlo technique. Nucleation is simulated on the basis of equations describing stored energy evolution and subgrain growth kinetics. The parameters describing the stored energy evolution during recovery are shown to influence not only the relative number, orientation and local distribution of nuclei, but also the recrystallization kinetics and the final texture. The estimated kinetics of nucleation, the mean stored energy evolution as well as the preferential texture of first nuclei are in agreement with experimental observations for annealing 40% cold-rolled IF-Ti steel and cold drawn copper wires.

Monte Carlo simulation of primary recrystallization and annealing twinning

“…Its value is in the range of 0.1 and 10 [28]. In the present paper, both influences were supposed to have the same level (C = 1).…”

“…The method described in Ref. [28] was used with some modifications. For a chosen pixel i (belonging to a nucleus), the driving force for its growth depends on the stored energy gradient DH ij , the GB energy cðh ij Þ and the mobility Mðh ij Þ (h ij is the misorientation between the pixel i and its jth neighbor).…”
