| Abstract Scope |
To study the effect of temperature and strain parameters of high strain rate torsion on the microstructure evolution of Al-based alloys, such as AA 5056 and AA 2024 T4, torsion tests were realized under the same conditions on Gleeble-3800 System, as well as numerical simulation in Deform 3DTM software. The tests were provided at elevated temperatures, with varying strain and strain rates. A qualitative and quantitative analysis of the studied alloys using optical microscopy were performed. The strain distribution according to the quantitative analysis of grain size in various zones was studied depending on the temperature and strain parameters of the torsion tests. A qualitative assessment of the stress/strain effect on the grain size according to the results of physical and numerical simulation was realized. The pattern of grain size evolution at different temperature and strain parameters of high strain rate torsion is established. |
