Severe plastic deformation (SPD) with deformation strain significantly larger than one is effective to strengthen metals and alloys. However

such a method will not work for Mg alloys due to their low deformability. In view of this problem

we propose a new alloy strengthening scheme of low-strain deformation

which is to introduce massive twins and stacking faults in coarse grain interior by rotary swaging (RS) at room temperature. By using this scheme

we successfully prepared an ultra-light bulk Mg-Li alloy with new strength record.
