| Abstract Scope |
The paper focuses on the development of a static recrystallization model of 6XXX aluminum alloy based on industrial profiles extrusion analysis. 6XXX aluminum alloys are widely used for complex shapes with smooth surfaces suitable for visible architectural applications. Mechanical properties and surface defects, for example, streaking lines, are dependent on the microstructure. Static recrystallization occurs in alloys such as 6XXX due to high stacking fault energy. At the moment, there is no reliable static recrystallization model of 6XXX aluminum alloys found in the literature. In the presented paper a new approach has been proposed to determine the parameters of Johnson-Mehl-Avrami-Kolmogorov equation. It is based on using of strain and temperature history during extrusion of industrial profiles and examining the microstructure in their cross-sections and implementing of the inverse analysis approach. The developed model has been verified and used for simulation of the microstructure evolution in industrial extrusion cases and has shown sufficient accuracy. |
