“…Due to the use of nuclear fusion and the third-generation nuclear fission reactors, zirconium-based alloys have been widely studied as important nuclear cladding materials [1][2][3][4][5]. This relies on their specific characteristics: excellent corrosion resistance, good mechanical properties, high resistance to radiation damage and a low cross section of capture for thermal neutrons [6].…”

The phase relations of the Fe-Zr-Y system at 973 K and 1073 K were experimentally investigated by using the equilibrated alloys. New ternary compounds τ3-Fe3ZrY and τ4-Fe10Zr5Y2 were found in this ternary system. The solubility of Y in Fe2Zr was measured to be 3.5 at.% and the third component can hardly dissolve in the other binary intermetallic phases. Experiments have verified that Fe2.9Zr0.5Y0.5 has a solid solubility ranging from Fe73Zr12Y14 to Fe77Zr9Y13.

“…It is of interest to establish a thermodynamic database for Ti(C,N)-based cermets to guide the manufacturing process or design advanced cermet materials [14,15] . The establishment of such a thermodynamic database requires the experimental data of the Mo-Ti-Zr [16] and some relevant systems [17][18][19][20] . The knowledge of phase equilibria and thermodynamic modelling of the Mo-Ti-Zr system is important to perform TZM or Ti-based biomedical alloy design and establish a thermodynamic database for Ti(C,N)-based cermets.…”

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.
