| Abstract: |
| A combination of experimental observation and computer simulation was employed to model recrystallization of copper deformed by simple shear extrusion (SSE). Simple shear extrusion was used for severe plastic deformation (SPD) processing of samples to reach a deformed structure with specified amount of strain. SSE was followed by annealing at different temperatures ranging from 210°C to 290°C and different soaking times. As a thermally activated phenomenon, softening caused by static recrystallization was obvious. Softening fractions calculation at different times and temperatures resulted in an investigation of JMAK equation constants. Static recrystallization resulted in a restored structure which was studied by optical microscopy as well as by Monte Carlo computer simulation at the same annealing temperature and times as the experimental ones. Microstructural inhomogeneity was simulated by imposing a distribution of stored energy calculated from experimental hardness values. The simulation results were compared with the experimental JMAK model results and an acceptable agreement was achieved. |
