The correct option is (b) False
Best explanation: The grain SIZE is highly affected by adding zirconium in magnesium metal. Addition of less than 0.6% zirconium in magnesium is SUFFICIENT to obtain grain size less than 80 microns in casted components. This further increases hardness in the material due to FORMATION of fine grains and ductility ALSO decreases simultaneously.
