Materials Science and Engineering: A, 2009•ElsevierThis article reports the effect of boron addition on the grain refinement efficiency and
mechanical properties of AZ91 magnesium alloy. The results show that the addition of boron
in the form of Al–4B master alloy, significantly refines the grain size of AZ91 alloy. This
refinement is due to the presence of AlB2 particles, which act as potential nucleants for Mg
grains. Improved mechanical properties are obtained with the addition of boron due to the
finer grains.
