A double-stage thermal treatment has been adopted on a Mg-Y-Nd-Zr (WE43) alloy, following suggestions of a previous calorimetric investigation. A secondary precipitation is claimed to occur at a temperature as low as 150 degrees C after a preliminary precipitation at 210 degrees C, with the effect of enhancing the hardness increase and reducing the annealing times.
