The use and adoption of magnesium extruded profiles in structural applications is limited because magnesium extrusion technology is at its conception. Once extruded hollow sections are available at a reasonable cost, a tremendous increase of market demand is expected due to the low weight of magnesium alloys in comparison with aluminum based ones.

Abstract
The use and adoption of magnesium extruded profiles in structural applications is limited because magnesium extrusion technology is at its conception. Once extruded hollow sections are available at a reasonable cost, a tremendous increase of market demand is expected due to the low weight of magnesium alloys in comparison with aluminum based ones. The press productivity represents a key factor in this scope. Also the die, due to the strong influence of strain and temperature on extrudability, will play a basic role in achieving the required ram speed. This paper present a new approach for designing extrusion dies specifically for magnesium alloys AZ31 and ZM21 by means of FEM simulation. The effectiveness of the new design has been validated by extruding a hollow profile using an industrial press with data logging.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
