Abstract
Hot rolling is an important thermomechanical processing technique used extensively in industrial metal production. Aluminum alloys are a common structural material and are generally hot rolled in the process of converting a cast metal ingot into a final or near-final structure. Hot rolling of aluminum leads to a complex deformed structure with inhomogeneous distribution of solute elements, second phase particles, and recrystallization. Recrystallization is the process whereby new, strain-free grains nucleate from a deformed structure and grow. Recrystallization is an important feature of hot-rolled products as recrystallized grains decrease mechanical properties. Particularly for applications using an as-rolled alloy, or machined from a single hot-rolled plate, controlling recrystallization is a critical concern in industrial thermomechanical processing with major economic implications. Improved understanding of the hot-rolling process through modeling can help optimize industrial practices. The purpose of this study was to perform experiments simulating hot rolling deformation— providing insight into conditions present during hot rolling relative to thermomechanical processing parameters. Results from this experiment will be utilized in a framework of a through-process hot rolling model.
