“…Figure 1 shows the X-ray diffraction (XRD) patterns of the as-cast TχZAB alloys with different amounts of Zr. XRD patterns confirm the existence of a single α phase (Liu et al , 2017) in TχZAB alloys [Figure 1(c)]. According to the binary phase diagram of Ti-Zr alloys, the alloying element Zr can be completely dissolved in the Ti matrix at any temperature.…”

“…Besides, the composition adjustment affects the microstructure and, in turn, the corrosion behavior of Ti alloys (Ji et al , 2020b; Chui et al , 2020). Liu et al (2017) have studied the influence of Zr addition on mechanical properties of Ti-Zr alloys and demonstrated that the grain refinement and solid solution strengthening enhanced the mechanical performance. Moreover, there are several reports about the effect of Zr content on the corrosion behavior of Ti alloys, mostly focusing on the dual-phase Ti alloys (Xia et al , 2016).…”

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.

“…Therefore, a new type of TiZr-based alloy was successfully developed with higher hardness, strength, and better anticorrosion properties than conventional Ti alloys [23,24]. The microstructure tailoring of the newlydeveloped TiZr-based alloy and its mechanical properties were evaluated [25][26][27], and its higher hardness and strength made it potentially useful for moving parts in aerospace. As known, the moving parts always undergo friction and wear during their service.…”

This study focused on the tribological performance and microstructure evolution of T20Z alloy after dry sliding in air and vacuum. After the tribological tests, normal load and sliding velocity were considered to be optimized based on specific wear rates using Taguchi technique. The results of S/N ratio showed that the optimization of the parameters was 10 N, 0.59 m s −1 for obtaining the minimum wear rates in both air and vacuum. Also, the worn surface and cross-section of T20Z alloy as well as wear debris and counterpart steel balls were analyzed by scanning electron microscopy. Raman spectrometer was performed to further analyze the worn surface. The topography of wear scar was observed using a three-dimensional optical profilometer. The microstructure evolution of T20Z alloy was analyzed by transmission electron microscopy. The results showed that the wear mechanisms in air varied from abrasive wear to delamination wear and severe abrasive wear, and the grain size was finally refined to nanoscale. In vacuum, however, wear mechanisms changed from slight abrasive wear to delamination wear and severe plastic deformation, and only the β phase was deformed.
