“…So, it is particularly necessary to choose a suitable heat treatment process to regulate the organization and adapt to its performance. S.G. Liu et al [ 14 ] studied the effect of the annealing process on the microstructure and mechanical properties of the TiZrAlB alloy, and the results showed that the microstructure type and grain size determined the mechanical properties of the alloy. Biphasic tissues exhibit the highest intensity, and fine spherical tissue exhibits the best combination of strength and ductility.…”

In this work, the Ti-20Zr-15Mo alloy in its hot-rolled state was annealed in different phase zones, and the effects of the annealing treatment on the phase composition, organization, mechanical and corrosion resistance properties of the alloy were systematically investigated. The results showed that the original β grains of the alloy had all recrystallized to form the β equiaxial grains when annealed at 800 °C, and the grains had been significantly refined. This allowed the alloy to reach a tensile strength of 1000 MPa, a maximum of 28% after stretching, and a significant increase in plasticity. Also, due to the single beta phase, there was no galvanic corrosion, making the alloy annealed at 800 °C have the best corrosion resistance.

“…The optimization of the composition of the material and enforcing different rolling deformation treatments for improving the alloy's strength has been reported in the literature. However, in the industrial field, in order to better adapt the structural material to the operating environment, it is necessary to apply a heating process during the synthesis of the structural material to obtain matching operating properties [9].…”

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.

“…Hence, Ti and Zr can form an infinite solid solution, which is highly desirable for large-scale applications. Therefore, several studies have been conducted on Ti-Zr alloys, such as Ti-Zr (Correa et al, 2014;Li et al, 2011), Ti-Zr-Nb (Geetha et al, 2004), Ti-Zr-Al (Jiang et al, 2014;Jiang et al, 2015) and Ti-Zr-Al-B (Liu et al, 2019;Liu et al, 2018;Liu et al, 2020;Li et al, 2019b;Ijaz et al, 2015), demonstrating the positive influence of Zr addition. Furthermore, Ti alloys experience harsh corrosive environments, such as marine and hydrochloric acid environments.…”

Purpose The purpose of this paper is to study the influence of Zr content on immersion and electrochemical corrosion behavior of Zr-containing Ti-based (TiZr) alloys. Design/methodology/approach The phase analysis of as-cast TχZAB alloys was carried out using X-ray diffraction. The microstructure of corrosion surfaces of the samples was observed using optical metallographic microscopy and scanning electron microscopy, equipped with energy dispersive spectroscopy. Findings The immersion test reveals that the corrosion is alleviated in the presence of a high amount of Zr, whereas pitting corrosion occurs when the Zr content is up to 40 Wt.%. Furthermore, the electrochemical analysis demonstrates that the corrosion resistance TiZr alloys is improved with increasing Zr content. Originality/value The TiZr alloys are promising candidates for high-end applications because of their excellent comprehensive properties. These alloys are usually used in marine or other harsh corrosive environments; therefore, it is essential to study their corrosion behavior.
