Establishment of Prediction Model of Microstructure and Properties of 3003 Aluminum Alloy during Hot Deformation
Journal Title: Materials Science-Medžiagotyra - Year 2019, Vol 25, Issue 4
Abstract
The 3003 aluminum alloy was deformed by isothermal compression in the range of deformation temperature 300 – 500 ℃ at strain rate 0.0l – 10.0 s-1 with Gleeble-1500 thermal simulator. A constitutive equation is established from the flow stress of the hot deformation. It is found that the average grain size of the 3003 aluminum alloy increases with the decrease of Zener-Hollomon (Z) value, and there is a linear correlation between them. The prediction model of the steady-state flow stress and the average grain size is established. The steady-state flow stress increases with the decrease of the average grain size. The microhardness of the 3003 aluminum alloy has a positive linear relationship with lnZ, and the relationship between the microhardness and the grain size meets the Hall-Petch equation, which can provide a reference for the microstructure control and rolling equipment selection of the 3003 aluminum alloy under hot deformation conditions.
