“…The specimens with fewer and no impurities, MGSi-II and EGSi, respectively, dissolved faster in liquid Al than the MGSi-I specimens with more impurities. Similar trends were observed by Yeremenko et al [16] who showed that 99.994 pct pure polycrystalline Mo dissolved more quickly in molten Al than 99.95 pct pure Mo, and that there was no difference in the dissolution rates of mono-and polycrystalline Mo of the same purity.…”

“…Studies of stationary solid additions were conducted to compare the dissolution kinetics of different additions in liquid Al, [7][8][9] to investigate natural convection mass transfer in liquid metal systems, [8,10,11] and to characterize the types of intermetallic layers formed at interfaces. [9] Experiments using rotating disks [12][13][14][15][16][17][18][19] or cylinders [7,20] of the addition were conducted to measure solute diffusion coefficients and to identify the dependence of dissolution rate on fluid flow conditions.…”

This manuscript presents research work related to the assimilation of Silicon (Si) in molten Aluminum (Al) under natural and forced convection conditions. The effects of impurity levels of solid Si, Al bath temperature, and fluid flow conditions were investigated. It was found that a polycrystalline metallurgical grade Si (MGSi) with higher levels of impurities dissolved more slowly than high purity polycrystalline MGSi, which showed a similar dissolution rate to monocrystalline electronic grade Si. For high-purity Si cylinders, the experimental data under natural convection conditions exhibit good agreement with a correlation for vertical cylinders: Sh ¼ ð0:11to 0:129ÞðGr m ScÞ 1=3 : Under forced convection conditions, by rotating the molten Al, the mass transfer rate increased at higher liquid velocities, implying that the dissolution process is controlled by liquid phase diffusion. When the forced convection prevails, the experimental data are well predicted by a correlation for vertical cylinders in cross flow:1þð0:4=ScÞ 2=3

The Al-Mo and Al-Fe-Mo systems were critically assessed using the CALPHAD technique. The solution phases (liquid, fcc and bcc) were described by a substitutional solution model. The nonstoichiometric compound AlMo 3 was described by a two-sublattice model (Al,Mo)(Al,Mo) 3 in the Al-Mo binary system and (Al,Fe,Mo)(Al,Fe,Mo) 3 in the Al-Fe-Mo ternary system. Other comin the Al-Mo system were treated as stoichiometric compounds in the binary system and as line compounds Al m (Fe,Mo) n in the Al-Fe-Mo ternary system. The compounds l and Fe 2 Mo in the Fe-Mo system were treated as (Al,Fe) 7 Fe 2 (Fe,Mo) 4 and (Fe,Mo) 2 (Al,Mo) in the Al-Fe-Mo system, respectively. ) 0.235 Al 0.6275 (Al,Va) 0.1375 in the Al-Fe-Mo system, respectively. Ternary compounds s 1 and s 2 were treated as Al 8 (Al,Fe)Mo 3 and (Al,Fe,Mo)(Va) 3 , respectively. A set of self-consistent thermodynamic parameters of the Al-Fe-Mo system was obtained.
