Study of the structure and properties of a wrought Al–Mg–Mn aluminum alloy on a Gleeble 3800 simulator designed for physical modeling of thermomechanical processes

Metallurgist Aims and scope

The mechanical behavior of aluminum alloy 5454, belonging to the system Al–Mg–Mn, is studied during hot plastic deformation on a Gleeble 3800 simulator designed for physical modeling of thermomechanical processes. The study was conducted under different temperature-rate conditions. Examination of the structure of the hot-deformed specimens showed that dynamic recrystallization is impeded in the alloy. The substructure obtained after deformation at 400°C consists mainly of equiaxed subgrains with dimensions of 1–2 μm, the exact size depending on the rate of deformation. A mathematical model that was constructed to relate the flow stress of the given alloy to the rate, temperature, and degree of deformation can be used for finite-element calculation of the properties of different sections of products of complex shape that are made of this alloy by various methods of hot plastic deformation.
