The topic of climate protection and, for example, the resulting need for a reduction in the use of fossil fuels, is a major focus of research. Particular interest is taken in the
substitution of traditional metals such as steel with lightweight materials like aluminium and magnesium alloys in the automotive and generally in the transportation sector. Due to the hexagonal crystal structure of magnesium, the processing of its alloys contains some almost unique challenges. By alloying calcium, for example in ZAX-alloys
– containing zinc, aluminium and calcium – the formability at room temperature is improved through a less pronounced texture with a basal pole split. [2] To join the replaced
components in the cars, welding can be used. This process profits from procedure where base and weld material are of similar compositions. For welding, and for
wire-based additive manufacturing too, wires with a diameter of approximately 1 – 1.6 mm are required, which can only be produced through drawing. The production for the
preliminary products can be achieved through either extrusion or groove rolling. For the latter there is a lack of fundamental empirical experience and research results that
are required for a successful application and implementation in the industry. The extrusion process is more established but groove rolling has the potential to produce larger quantities in the same time and has the added advantage of a greater grain refinement.
