Abstract Scope |
Magnesium predominantly exhibits a hexagonal lattice structure. The anisotropic distribution of activatable slip systems often leads to crystallographic preferential orientations during forming, whereby the anisotropic crystallographic properties show up macroscopically as anisotropic mechanical properties in components.
Efforts to improve materials and optimize them should not only consist of mitigating or even preventing such anisotropic component properties. There is great potential to exploit them constructively.
For this purpose, a 6x3 process matrix was designed using the magnesium alloy AZ31 as an example to investigate the influence of different forging as well as forming routes on the properties of extruded round bars. Six different initial states of extrusion billets and three different extrusion dies were used, one designed for double equal channel angle extrusion (ECAPEX).
Forming behavior as well as microstructure and mechanical properties were investigated. Selected examples are used to present the results and evaluate the various influencing factors. |
