Deep Drawing Formability Analysis of AZ31 Mg-Alloy


Article Preview

Light and highly resistant, magnesium has been more and more included into alloys composition, especially in automotive and electronic devices. Usual automotive applications for magnesium alloys are gearbox, cylinder head covers and other types of covers, when electronic industry uses this alloys for mobile computers and mobile phones frames (chassis). However casting is still the first production process for magnesium application, press forming is considered as having significant potential. Yet, influences of many key parameters are not clearly known. In this report, sheets of AZ31 magnesium alloy were submit to deep drawing tests to investigate the influence of temperature, lubricant, blank holding pressure and speed. As a result, an appropriate lubricant was selected out of a set of potentially interesting lubricants selected with respect to their announced properties. Deep drawing tests also enlighten the poor formability of AZ31 even at 160°C and an apparent optimum formability temperature at 200°C. Other tests and controls, like thickness profile, were also performed to complete knowledge of AZ31 properties.
