Coarse grain issue at the ends of 2A50 aluminum bar
Why coarse grain rings occur?
During the later stages of extrusion of 2A50 aluminum bars, when the metal flowing towards the center of the product reaches or approaches the critical level of deformation, coarse grain ring structures form after quenching.
Process measures to reduce coarse grain rings in 2A50 aluminum bar
Optimization of alloying elements: Elements such as Mn, Fe, and Ti in 2A50 aluminum alloy can increase the recrystallization temperature and suppress grain growth. The second-phase particles formed by Mn are dispersed and effectively prevent grain coarsening. The presence of Mg and Si, which form Mg2Si compounds, also helps control grain size. During extrusion, the outer metal experiences a stress gradient due to friction, promoting the precipitation of Mn particles and lowering the recrystallization temperature, thereby reducing coarse grains at the surface.
Lubricated extrusion: Lubricated extrusion reduces friction between the metal and the inner wall of the extrusion die, decreasing the extent of grain fragmentation in the shear deformation zone and avoiding excessive grain growth. However, excessive or improper lubrication can leave oil residues on the surface, affecting product quality.
Appropriate extrusion speed: Lower extrusion speeds result in smaller and more uniform grains, reducing the likelihood of coarse grain rings. At high extrusion speeds, the friction between the metal and the die increases, leading to shear deformation and coarse grains.
Suitable extrusion temperature: At low temperatures, the surface deformation of the metal is insufficient to form coarse grains. At high temperatures, increased grain distortion energy facilitates recrystallization, which may lead to the formation of coarse grain rings.
Influence of extrusion die: An excessively long die reducing section increases the friction area between the surface metal and the die, causing surface metal flow to lag and exacerbating the formation of coarse grain rings. Optimizing the length of the reducing section can effectively reduce coarse grain structures.
