Forgeability of modified AZ and ZK wrought magnesium alloys
conference paper
Wrought magnesium alloy products have favourable attributes compared to castings with regard to mechanical properties. In addition they provide a complementary class of shapes and geometries. These are the current drivers for developments within the field of magnesium
forging technology. Within this context, the European research project MagForge is being conducted with the overall goal to provide tailored and cost-effective technologies for the industrial manufacturing of forged magnesium alloy components. One of the present impediments to magnesium forging is the availability of suitable alloys: Forgeability in terms of the robustness of processing windows and the resulting product quality in terms of mechanical performance need to be improved. Hence this is one of the main topics of the project. This paper reports on the progress made in this particular area. The strategy adopted for advancement consists in inducing grain refinement and stabilisation of the microstructures by rare-earth and complementary modifications of the commercial AZ80 and ZK60 forging alloys. In line with common practice, forging slugs were prepared from cast billets by preextrusion. The quality of the modified alloy slugs is assessed on the basis of laboratory-scale cone-forging trials. The results show a significant improvement over the existing alloys.
