【 摘 要 】

We have successfully developed a Mg-3Al-0.4Mn (wt%) alloy sheet with good room-temperature formability. The alloy sheet shows a large Index Erichsen value of 8.2 mm due to its unique texture feature where the most of the grains have circular distribution of basal poles away from the normal direction of the sheet. The fine grain structure also leads to moderate strengths and large ductility with in-plane isotropic tensile property. These mechanical properties could be realized via industry viable rolling processing, thus the alloy sheet is highly possible to broaden the applications of Mg alloys in automotive industries.
