Abstract: | Copyright © 2016 The Authors. A quantitative model was applied to analyse the grain refinement potency of bismuth in magnesium. The formation of potent Mg-Bi-O intermetallic phases at 0.4wt.% Bi were attributed to a noteworthy reduction in the average grain size of α-Mg grains. The efficiency of the grain refiner was identified through the analysis of grain size vs inverse of the growth restriction factor (Q) plots, with a comparison of the Zr solute under similar experimental conditions. It was concluded that ‘Q’ could be a suitable predictor of the relative grain size in the Mg-Bi system containing potent nucleant particles. The cooling rate analysis supported the efficiency of bismuth grain refinement in magnesium. |
