A Processing map has been developed for Magnesium alloy AZ31 extruded at 450 °C which revealed that the extruded rods may be further processed into components industrially at 400 °C and at a strain rate of 10 s –1 . If processed at lower strain rates in the vicinity of 0.1 s –1 , unusual grain size variations with temperature and strain rate are observed, suggesting that grain size control will be difficult.
