“…19 Through phase-field (PF) simulation linked to CAL-PHAD databases, Eiken et al showed that critical threshold amounts of P and Sr are needed for the pre-silicon formation of AlP and Al 2 Si 2 Sr, respectively. 45 The threshold for P was found to be between 3.2 and 3.8 ppm, where the lower-bound was obtained from PF simulations due to the additional consideration of nucleation undercooling. Thus, the minimum P level to form AlP is indeed well below the commercial purity standards of Al-Si alloys.…”

“…eutectic Si nucleated with high frequency on AlP with minimal undercooling. 45 The solidification pathway for supercritical Sr levels [Fig. 5(b)] is notably different: Al 2 Si 2 Sr poisons the AlP particles, which results in a retarded nucleation of eutectic Si.…”

“…As an excellent wear-resistant material, hypereutectic AlÀ Si alloy has been used in the preparation of engine parts [2]. With the increase in silicon content, the density and linear expansion coefficient of the alloy decrease, and the thermal stability of the alloy increases [3].…”

“…The mathematical computation and simula-tion can be reasonably effective in predicting the detailed insight into the dynamic evolution of microstructure [21,22]. For example, Eiken et al [23] reported the impact of the addition of P and Sr on solidification sequence of AlSi alloys by means of the thermodynamic computation. Researchers have also elucidated the evolution of the eutectic morphology using the 3D phase-field simulation.…”
