| Abstract |
Nucleation and normal or abnormal grain growth of new grains have been observed in
several metals and alloys during annealing after various levels of strain (from few percents for
abnormal grain growth in steel and aluminium to 90 % strain for static recrystallization of highly
deformed copper, zirconium and steel). For each of these cases, the links between the initial
deformation state of the polycristalline samples and their final textures after annealing are analyzed
in some details, by taking into acount the distribution of orientations and misorientations within the
samples, as well as the repartition of stored energy . With the help of polycristalline models for the
simulation of deformation and recrystallization processes, some general conclusions regarding the
nucleation and growth processes are finally drawn. |
