Consumption of wrought magnesium products wax reduced by half between 1971 and the 1990s. To increase the use of wrought magnesium, several challenges must be overcome: its formability at room temperature is lower than steel or aluminum; its productivity is lower than steel or aluminum; and extruded magnesium exhibits a marked anisotropy of yield when comparing tension and compression. This article describes research on the rapid evaluation of the extrusion behavior of wrought magnesium alloys. The work aims to establish a methodology for rapid prototyping of alloys and to assess the effects of aluminum on the behavior of AZ-series magnesium alloys.
