dc.description.abstract | Following the discussion of modeling grain refinement in Part 1, [X. Yao, et al., J. Mater. Res. 23(5), 1282, the effect of Al-Ti-B master alloy additions on grain formation in commercial-purity (CP) aluminum was investigated. The characteristics of the addition particles as applicable to the model are presented. The effect of adding TiB2 particles, the introduction of extra particles by reactions in the melt, and the effect of adding extra solute Ti are all modeled. The distribution of the potential particles and its effect on grain formation was also modeled to establish the relationship between the grain size and microstructure morphology and the additive characteristics. The calculated results are comparable with experimental data. Accordingly, possible mechanisms of grain refinement with Al-Ti-B refiners were proposed. | |
