摘要: Abstract The strain-rate effect in die-cast magnesium-aluminium based alloys under quasi-static strain rates ranging from 10−6 to 10−1 s−1 was investigated. sensitivity shown decrease with increasing aluminium solute level the matrix. Microstructural examination by electron backscattered diffraction (EBSD) revealed that deformation twinning is more active lower sensitivity. It suggested likely due dynamic ageing interaction between and dislocations. correlation ductility AE44 briefly discussed.
