“…All experimental investigations found in the literature on thermodynamic properties and phase equilibrium data of the binary Al-P 900-1200 0-0.005 [42] Solubility of P in liquid Al Controlled high temperature filtration experiments 690-1000 0-0.0007 [43] system are collected in Table 2 [14,35,[37][38][39][40][41][42][43]. The standard enthalpy of formation of AlP, Δ f H1(AlP), was experimentally measured by several researchers independently [14,35,37,38].…”

“…Later, Lescuyer et al [43] also measured the phosphorus solubility in liquid Al using high temperature filtration experiments. They criticized that Beer′s [42] solubility values were too high because some dissolved AlP crystal might re-precipitate in the melt.…”

“…Based on the theory proposed by Beer and Lescuyer et al [27,28], the solubility of AlP can be calculated by the equation: log(x p ) = 0.684-, in which x p is the molar fraction of soluble phosphorus (T, the Kelvin temperature). Meanwhile, the soluble phosphorus would precipitate during the solidification process and act as heterogeneous nucleation sites of primary Si phase.…”

In this article, a novel Al-6Y-2P master alloy with cubic YP particles was successfully synthesized and its complex modification performance on Al-18Si alloy has also been investigated. With the doping of La and Ce, (YxLa1-x)P and (YxCe1-x)P particles still exhibit cubic morphologies in three dimensional spaces (3-D space). The excellent complex modification of Al-18Si alloy can be obtained with the addition of Al-6Y-2P master alloy. Under the optimized conditions, i.e. melting temperature of 780°C, addition level of 1.5 wt% and holding time of 30-60 min, the tensile strength and Brinell hardness of Al-18Si alloys can be significantly increased by 16.8% and 17.1%, respectively. It is proposed that the Si atoms in the melt could promote the structure evolution of YP to AlP with the release of Y, which would be reason for the excellent composite modification performance of the developed Al-6Y-2P master alloy.

“…Prior work shows that primary Si nucleates heterogeneously on the solid AlP particles with a cubic-cubic orientation relationship and solidifies, thereby promoting the refinement of primary silicon. [41][42][43] Most of the commercial Al-Si alloys invariably contain small amounts of phosphorus leading to the formation of AlP particles. Many of the AlP particles cannot be absorbed by the Al melt because of the lower solubility of phosphorus as well as the density differences.…”

Although the grain-refinement practice is well established for wrought Al alloys, in the case of foundry alloys such as near eutectic Al-Si alloys, the underlying mechanisms and the use of grain refiners need better understanding. Conventional grain refiners such as Al-5Ti-1B are not effective in grain refining the Al-Si alloys due to the poisoning effect of Si. In this work, we report the results of a newly developed grain refiner, which can effectively grain refine as well as modify eutectic and primary Si in near eutectic Al-Si alloys. Among the material choices, the grain refining response with Al-1Ti-3B master alloy is found to be superior compared to the conventional Al-5Ti-1B master alloy. It was also found that magnesium additions of 0.2 wt pct along with the Al-1Ti-3B master alloy further enhance the near eutectic Al-Si alloy's grain refining efficiency, thus leading to improved bulk mechanical properties. We have found that magnesium essentially scavenges the oxygen present on the surface of nucleant particles, improves wettability, and reduces the agglomeration tendency of boride particles, thereby enhancing grain refining efficiency. It allows the nucleant particles to act as potent and active nucleation sites even at levels as low as 0.2 pct in the Al-1Ti-3B master alloy.
