“…Microscopic structures, such as phase composition, grain size, shape and composition distribution in matrix, greatly influence the mechanical properties of alloys [1][2][3][4][5][6][7]. Grain refinement in solidification process has been presented many advantages, including forming a more homogeneous microstructure and obtaining excellent mechanical properties.…”

“…Importantly, ω and α″ phases are too fine to be observed through the backscattered image. Previous research has shown that the martensite phase transformation from β→α″ takes place during water quenching in Ti‒Al‒V‒Zr alloys [ 12 ]. This result means that the quenched Ti‒6Al‒4V‒30Zr alloy was comprised mainly of the β-and α″ phases, which could be verified in the TEM results.…”

“…Schmuki [ 7 ], Liu [ 8 ], and Ho [ 9 ] have investigated the microstructure and mechanical properties of Ti–Zr binary alloys, and the results have shown that the phase composition and mechanical properties of these binary alloys varied remarkably with changes in Zr content. Moreover, previous studies [ 10 , 11 , 12 , 13 ] showed that Zr had significant influence on the properties of many multicomponent Ti alloys. The influence of Zr content on the structure and properties of ternary Ti–Nb–Zr alloys was investigated by Zhou [ 10 ], and the result showed that increasing Zr content decreased the strength of the alloy but increased the ductility.…”

“…Chen [ 11 ] investigated the effect of Zr on the structure and mechanical and thermal properties of Ti–Al–N-based coating, and noted that the addition of Zr promoted the formation of cubic domains and retarded the formation of stable wurtzite AlN, which led to high hardness during thermal annealing. Liang [ 12 ] investigated the microstructure and mechanical properties of Ti–5Al–3V–30Zr alloy that has undergone various annealing heat treatments, and the alloy has shown good mechanical properties. However, the strengthening mechanism and phase transformation of the Ti–5Al–3V–30Zr alloy has not yet been reported.…”

The influence of various Zr contents (0–45 wt.%) on the microstructure and mechanical properties of Ti6Al4V alloy was investigated through a combinatorial approach. The diffusion multiples of Ti6Al4V–Ti6Al4V20Fe–Ti6Al4V20Cr–Ti6Al4V20Mo–Ti6Al4V45Zr were manufactured and diffusion-annealed to obtain a large composition space. Scanning electron microscopy, electron probe micro-analysis, and a microhardness system were combined to determine the relationships among the composition, microstructure, and hardness of these alloys. The Ti–6Al–4V–30Zr alloy was found to contain the thinnest α lath and showed peak hardness. X-ray diffraction and transmission electron microscope results indicated that after quenching from the β-field, the metastable α″-phase formed; moreover, at the secondary aging stage, the metastable α″-phase acted as precursor nucleation sites for the stable α-phase. The bulk Ti6Al4V30Zr alloy was manufactured. After aging at 550 °C, the alloy showed excellent balance of strength and ductility, and the tensile strength was 1464 MPa with a moderate elongation (8.3%). As the aging temperature increased, the tensile strength and yield strength of the alloys rose, but the total elongation decreased. The lamella thickness and volume fraction of the α-phase were the major factors that had great impacts on the mechanical properties.

The influence of various Fe contents on the microstructure and mechanical properties of Ti-30Zr-5Al-3V (ZTAV) alloy was investigated. After Fe addition, the grain refinement is obvious and the phase composition changes as α'+β→β. Ti-30Zr-5Al-3V-0.5Fe exhibits a better mechanical property (σ b ≈1420 MPa, ε f ≈5.34%) than Ti-30Zr-5Al-3V (σ b ≈1302 MPa, ε f ≈4.28%). Highest ultimate tensile strength (σ b ≈1667 MPa, ε f ≈2.34%) have been achieved in Ti-30Zr-5Al-3V-1.5Fe. The mechanical properties change owe to the phase transformation, grain refinement, and solid solution strengthening caused by Fe addition.
