| dc.description.abstract | The microstructural evolution related to the superplastic response of an AllOMg- O.lZr alloy during thermomechanical processing (TMP) was studied. The TMP had been accomplished in previous work and consisted of 12 rolling passes, with reheating between each pass, to a total strain of 2.5. Quantitative data including length, aspect ratio and area of precipitated 6-phase (Al8Mg5) particles were obtained using image analysis methods applied to the as-rolled conditions following passes 8, 10 and 12. The corresponding accumulated suains were 1.5, 2.0 and 2.6, respectively. Precipitation of the 6-phase is complete by pass 8 and the size as well as the size distribution remained essentially unchanged in the subsequent passes. A model for particle- stimulated nucleation of recrystallization, which is based on thermodynamic considerations, is evaluated with respect to experimental data. | en_US |
