Effect of homogenization annealing on the casting microstructure and properties of 6061 aluminum alloy billets
The experiment was conducted on the effect of homogenization annealing on the casting microstructure and extrusion properties of 6061 aluminum alloy billets.The results show that the annealed 6061 aluminum alloy billets have more homogenized casting micro-structure due to elimination or reduction of internal stress and intragranular segregation.Compared with the non-annealed billets,the annealed ones have 10%-20%lower extrusion breakthrough pressure and better surface.This experiment provides a reference for optimizing the extrusion process of 6061 aluminum alloy.
