Monte Carlo Simulation grain growth EBSD, isotropic anisotropic artificial
matrix kinetics grain size distribution texture. |
Index. décimale : |
530 Physique |
Résumé : |
In this work, we are interested in the Monte Carlo simulation of the influence of anisotropy on
the normal growth of grains in an IF steel. We used three matrices to initialize the simulation:
experimental obtained by EBSD and two artificial, isotropic and anisotropic, generated by
computer. The growth kinetics show values of the growth exponent that are higher than its
theoretical value. The microstructural evolution during the simulation shows similar grain size
distributions and the self-similarity is preserved during the experimental evolution and in
simulation. For the simulation textures evolution, orientations remain near randomly
distributed in the orientation space during grain growth for the isotropic matrix, grain growth
leads to reinforce homogeneously the orientations inside γ fiber for the anisotropic
experimental and artificial matrices. However, the maximum values of the ODF are observed
for the {111}<112> and {111}<110> components for these two states, repectively. On the
other hand, the experimental evolution leads to the reinforcement of the {111}<110> at the
expense of the {111}<112> component in the interior of γ fiber. Introducing reliable
hypotheses on the mobility of grain boundaries can bridge the gap between simulation and
experience. |
