α-Al grains surrounded by Al-Si eutectic as the substructures in AlSi10Mg alloy fabricated by selective laser melting (SLM) were investigated in detail using three-dimensional atom-probe and transmission electron microscopy. Quantitative analysis of α-Al revealed (1) the formation of Mg clusters and Mg-Si co-clusters with a density in the order of 1023 /m3 in α-Al of the as-built state caused by the complicated thermal history, and (2) a supersaturated Si content that significantly exceeded the maximum solubility due to rapid solidification, during the SLM process.

“…Therefore, we here investigated the temperature corresponding to f S →1 using f S −t curves calculated with TC under the modified Scheil model [18], which is widely used for conventional ingot casting. Because this model takes the solid diffusion of some interstitial atoms (such as C and N) into consideration, it is regarded to be more accurate than the traditional Scheil model in describing the solidification behavior of real ingots.…”

The liquidus and solidus temperatures of FeCrAl stainless steel were determined by differential scanning calorimetry (DSC) at different heating rates. They were also calculated by Thermo-calc software and empirical formulae separately. The accuracy of calculation results was assessed by comparison with the corresponding DSC results. The liquidus temperatures calculated by empirical formulae, which exhibited a maximum deviation of 8.6°C, were more accurate than those calculated using Thermo-calc, which exhibited a maximum deviation of 12.11°C. On the basis of Thermo-calc calculations performed under the Scheil model, the solidus temperature could be well determined from solid fraction (f S ) vs. temperature (t) curves at f S = 0.99. Furthermore, a theoretical analysis to determine the solidus temperature with this method was also provided.

“…The Scheil solidification simulation is a very effective method to predict crystallisation sequences and phase constitution during cooling. The structures and the compositions of the various phases which precipitate can affect casting properties [58] , microstructures and mechanical properties [59] . However, it is difficult to determine the crystallisation sequences through microstructure analysis.…”

Thermodynamic information of the Mo-Ti-Zr ternary system is extremely useful to provide guidance for biomedical alloy development. In the present work, the experimental data available from the literature were critically reviewed, and a thermodynamic modeling of the Mo-Ti-Zr system was performed using the CALPHAD (CALculation of PHAse Diagram) approach. The solution phases including liquid, bcc_A2 (β) and hcp_A3 (α) were modelled by the substitutional solution model, and the laves_C15 phase was modelled using a two sublattice model. In the Mo-Ti-Zr system, there is no ternary compound. A set of self-consistent thermodynamic parameters were developed. Comprehensive comparisons between the calculated and measured phase diagrams suggest that the experimental information is satisfactorily accounted for by the present thermodynamic modelling. The discrepancies between the calculated and measured phase equilibria have been well explained in this work. With regard to the β phase, the miscibility gap and related phase relations are well described by the present calculation. The liquidus projection and Scheil solidification simulation were generated using the present thermodynamic parameters. The presently calculated phase diagrams of the Mo-Ti-Zr alloys can be used in the biomedical field. Based on the calculations in the present work, two guidelines were formulated to avoid the laves phase formation in these frequently studied Mo-Ti-Zr biomedical alloys.
