“…Molybdenum alloys are extensively utilized in various fields such as metallurgy, the chemical industry, and the military due to their exceptional properties including high-temperature resistance, strength, stiffness, and low coefficient of thermal expansion [1][2][3] . Among these alloys, TZM alloy stands out with its remarkable melting point of 2617℃, making it highly suitable for applications in aerospace where high-temperature parts are involved [4][5][6] .…”

TZM alloy billets were fabricated using powder metallurgy (PM) and powder metallurgy + hot isostatic pressing (PM+HIP) techniques, and the influence of these two processes on the microstructure and mechanical properties of TZM alloy billets was compared. The experimental findings indicate that an enhanced hot isostatic pressing process effectively reduces the internal porosity of TZM alloy, leading to increased tensile strength and elongation at room temperature. However, there is no significant improvement in hardness and tensile strength at 600℃.

“…Extensive phase diagram data of the Mo-Ti-Zr system are available in the literature [16,[21][22][23][24][25][26][27][28] . Kar et al [29] optimized the Mo-Ti-Zr system incompletely, and excluded the miscibility gap in the bcc_A2 phase. Since a reliable thermodynamic description for the whole Mo-Ti-Zr system is still unavailable in the literature, the present work aims to obtain a set of self-consistent thermodynamic parameters for the ternary system by means of the CALPHAD approach and provide a guidance for Mo-Ti-Zr biomedical alloys design.…”

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.
