Abstract

Deformation behaviour of microcrystalline and nanocrystalline (nc) Mg-5%Al alloys were investigated using instrumented indentation tests. The hardness values exhibited significant indentation size effect (ISE), with nc alloys showing weaker ISE. Relative higher strain rate sensitivity and inverse Hall–Petch relationship were observed in the nc alloys. This is attributed to highly localized dislocation activities and relative smaller activation volume, as compared to their mc counterparts. It is believed there is an increasing role of grain boundaries in plastic deformation mechanisms with decreasing the grain size.
