 The 2198 Alley alloy is a special type of aluminum alloy that exhibits superior mechanical properties when subjected to high strain rates and temperatures. This study examined its behavior under these conditions using a Glebel 1500 thermo-mechanical simulator. The researchers determined the alloy's rheological properties and identified the regions where it is most prone to instabilities. They also observed the microstructural changes that occurred as a result of the deformations, including the formation of dislocations and precipitates. Finally, they concluded that the alloy's behavior can be described by a modified version of the Arrhenius equation, which takes into account the effects of strain rate and temperature.
