“…Moreover, the β-phase volume fraction and grain size in the alloy increase with the annealing temperature, while the excessive grain size is not conducive to the overall mechanical properties of the alloy. Thus, the annealing temperature of Zr-Ti-based alloys should not be made too high [15,16].…”

In this experiment, an annealing treatment was carried out for a rolled Zr–Ti–8V alloy, and the toughening mechanism of the material was thoroughly analyzed by combining advanced material characterization and other testing methods. The phase composition of the Zr–Ti–8V alloy was sensitive to the applied annealing temperature, while a series of changes in the phase composition of the alloy were induced by enforcing bigger thermal budgets. Implementing a temperature value of 450 °C led to a higher α-phase content, in striking contrast with the case where a lower annealing temperature of 400 °C was applied. The β grains that were stretched in the alloy’s rolling direction and annealed at 600 °C to 800 °C were recrystallized. As a result, the acquired configuration was equiaxed with β grains. The extracted results revealed that the alloy annealed at 450 °C showed a good strong–plastic ratio, with tensile strength and elongation of 1040 MPa and 8.2%, respectively. In addition, the alloy annealed at 700–800 °C showed good plasticity properties. From the hardness tests and friction wear experiments on all the experimental alloys, it was demonstrated that the dual-phase alloy with α + β had higher hardness and wear resistance, whereas the opposite trend was observed for the single β-phase alloy.

Zirconium (Zr) alloys have been widely applied in nuclear reactors due to their low probability of neutron capture, acceptable mechanical properties, and excellent corrosion resistance. [1-6] Zirconium alloys are commonly used as cladding tubes, fixed grids, or channel box in reactors. [2,3,6] The fabrication of Zr alloys components generally includes vacuum consumable melting, forging, extrusion, hot and cold rolling, recrystallization or stress relief annealing and so on. [7] Rolling and subsequent annealing are frequently used in the Zr alloy sheet and tube production, which actually determine the microstructure and texture, [7-10] thus playing a decisive role for the corrosion resistance, [11-14] creep resistance [15-17] and mechanical properties [18-20] of Zr alloys. Annealing can reduce the residual stress, recover the plastic deformation ability and tailor the grain size and texture, which plays a vital role in the Zr alloy fabrication. A special parameter was thus proposed to evaluate the effect of annealing. [21] The microstructure and the texture evolution during annealing are not only significantly affected by annealing condition, for example temperature [22,23] and holding time, [8,24] but also by the pre-annealing deformation. [6,25] Indeed, many research results on deformation and subsequent annealing in Zr alloys have been reported. Chen et al. [7] reported that the 30% rolling reduction combined with annealing at 580 C for 12 h imparted a superior plasticity to the Zr alloy. Kumara et al. [26] investigated the three stage of annealing in a moderately deformed Zr-4 alloy. They found that the changes in the misorientations, and corresponding rearrangements of dislocations, were the most efficient means of stress relief in Zr-4 alloy. Prakash et al. [27] investigated the microstructural and textural evolution of ZIRLO alloy during hot rolling at different temperatures. Their results show that the slip, twinning, and recrystallization played a role in the microstructure development during hot rolling. They also contributed to the texture development, lamellae break-up, and the formation of a bimodal microstructure. Jiang et al. [28] studied the effects of cold-rolling reduction, annealing temperature, and time on recrystallization behavior and kinetics of cold-rolled Zr-1Sn-0.3Nb-0.3Fe-0.1Cr alloy and found that the rate of the recrystallization increased with increasing annealing temperature and rolling reduction. Recrystallized grains nucleated preferentially at sites with high-density dislocation and deformation stored energy. Zhang et al. [29] studied the microstructure evolution and mechanical properties of Zr 98.2 Cr 1.8 during hot rolling, solution and aging treatment (STA). It was found the bimodal microstructure was the key factor to achieve high strength (ultimate tensile strength 818 MPa) and excellent ductility (18.4%) after STA at 750 C. Gerspach et al. [30] investigated the texture stability during primary recrystallization of cold-rolled Zr702 alloy and found that a small strain favored...
