title = "Effect of strain rate on mechanical behaviour of commercial die-cast magnesium alloys",
abstract = "The tensile properties of high-pressure die-cast Mg-6Al-0.3Mn (AM60), Mg-9Al-1Zn (AZ91), and Mg-4Al-4RE (AE44), under strain rates ranging from 10-6 to 10-1 s-1 have been investigated. It was found that AE44 is highly strain rate sensitive, followed by AM60, whilst AZ91 has little strain-rate sensitivity, fitting with previous observations about a correlation between strain-rate sensitivity and the aluminium content. Ductility is improved at lower strain rates in AE44 and AM60, but it appears to be independent of strain rate in AZ91. The difference in strain-rate sensitivity among these alloys is considered to be related to dynamic strain aging (DSA) from interactions between the aluminium solute and dislocations.",
