The evolution of microstructure and hardness with equivalent strain was studied in magnesium alloy AZ31 bars fabricated using a process of multi‐pass caliber rolling at 473 K. The inhomogeneity of hardness throughout the cross section in the rolled bars was very similar to that of the strain predicted from FE simulation. The caliber rolling produced a fine‐grain structure below 2.5 µm in a bulk sample with a length of over 1000 mm.
