Formability of Magnesium Alloys

The paper is focused on issues of processing of non-ferrous metals in practice, namely on Mg-Al-Zn based on magnesium alloys with graded Al contents. It is well known that forming of these alloys is difficult since this feature is caused by their crystallographic arrangement. Nevertheless, application of appropriate methods of forming, such as e.g. some of SPD processes, makes it possible to achieve even in these alloys with comparatively very low formability very good results with orientation on their final mechanical properties, not only strength but also proven plastic properties. Methods ARB a ECAP were used in the described experiment.
