- Abstract
- This paper mainly concerns application of the Mg-Al-Sn-Zn alloy to the control-arm of an automobile with warm-forging process since Mg-Al-Sn-Zn alloy (ATZ842) exhibits enhanced strengths in tension and compression as well as the improved YR reaching 1.0. In order to validate the Mg control-arm, two wrought Mg alloys such as AZ80 (Mg-7.45wt% Al-0.38wt% Zn) and ATZ842 (Mg-7.59wt% Al-3.96wt% Sn-1.94wt% Zn) alloy have been produced with casting and extrusion processes, which have been applied to warm-forging of the Mg control-arm. As-forged two Mg control-arms with AZ80 and ATZ842 alloys have been evaluated with the static strength test to measure the maximum reaction force under the quasi-static compressive deformation. It is highly recommended to adopt the ATZ842 control-arm forged at 250A degrees C since it does not only have comparably high reaction force in the static strength test, but also demonstrates fine grain structure if the abnormal grain growth is suppressed during the warm-forging process.
