Sheet metal production of magnesium
Magnesium alloys show a small forming capacity in the cast condition. The cast alloy in its structure is grain-refined by extrusion, so that the semi-finished indicates good transforming characteristics. These semi-finished material with the good warm transforming behavior were used for sheet metal production. The semi-finished material possesses a preferred direction and an extruding texture with high anisotropy by the extruding. For a good subsequent treatment a sheet metal is to produce with small anisotropic values, so that flowing in all directions runs evenly. For this reason three different rolling versions were examined for their influence concerning the shaping and the texture formation. The classical transform-relevant characteristic values and their predicate concerning deep-drawing security, are portable to the magnesium alloys AM20 and ZRE1. The determined characteristic values predicted the results of the sheet metal check. The measurements of the sheet metals by pole figures finally acknowledged the predicates. It is to be detected clearly that the rolling variation and the pre-conditioning direction have an influence on the later transforming characteristics of the sheet.
