The Mg-30B(2)O(3) modifier with the composition of Mg and B2O3, sintered in the temperature range between 250 and 450 degrees C, has been developed as a low-cost and effective modifier for hypereutectic Mg-Si alloys. With 0.2-1.0 wt.% B (introduced in the form of Mg-30B(2)O(3)), die morphology of the primary Mg,Si transforms from coarse dendrite shape into fine polyhedral shape with the size about 10 mu m. The
