Abstract (en)
Producing of profiles from a magnesium-based alloy, comprises extrusion molding a magnesium-based alloy comprising zinc (2-7%), zirconium (0.1-1%), calcium (0-0.5%), rare earth elements (0.8-4%), other elements (greater than 0.30%) and magnesium (remaining amount) at an extrusion molding rate of greater than 3 m/minute.
Abstract (de)
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Profilen aus einer Magnesiumbasislegierung durch Strangpressen, dass dadurch gekennzeichnet ist, dass die Magnesiumbasislegierung (m) 2.0-7.0% Zink, (n) 0.1-1.0% Zirkon, (o) 0.0-0.5% Calcium, (p) 0.8-4.0% Seltenerdelemente, (q) < 0.30% andere Elemente, (r) Magnesium als Rest, enthält. Mit diesem Verfahren lassen sich Magnesiumbasislegierungen mit überraschend hohen Geschwindigkeiten strangpressen.
