摘要: Abstract The high temperature deformation behaviour of AZ31 magnesium alloy is analysed by comparing numerous investigations, including work these authors and other researchers. Three main mechanisms are observed, i.e grain boundary sliding, solute drag creep climb-controlled dislocation creep. A combined set constitutive equations, which takes into account the concurring effect different mechanisms, proposed. Grain sliding observed to cause a superplastic in fine-grained materials, but growth due excessively prolonged exposure invariably results transition either viscous glide or climb as rate-controlling mechanism. On basis considerations, differences testing same material under constant strain rate change experiments rationalised quantifying static dynamic recrystallisation. This procedure provides unitary description wide range rates temperatures.
