“…The rolling temperature, rolling reduction, rolling load, and the rolling torque played significant effects in the rolling process. [7][8][9][10][11] Wang et al 12 adopted two rolling strategies to assess the impact of rolling temperature on the microstructure of large container ship steel. The findings showed that the acicular ferrite (AF) content increased with the decreasing finish rolling and cooling temperatures.…”

The effects of the rolling process and microstructure on the brittle crack initiation and arrest of marine steel were systematically investigated. The microstructures of two steel plates produced by different rolling processes were observed and analyzed. The results demonstrated that the rolling process significantly influenced the microstructure. As the rolling temperature decreased, the grain size decreased, the high‐angle grain boundary (HAGB) content increased, and the average grain misorientation angle increased. The brittle crack initiation and the arrest abilities were evaluated by initiation fracture toughness and crack arrest toughness, respectively. The initiation fracture toughness and crack arrest toughness increased with the decreasing grain size and the increasing content of HAGBs. Finally, the influence of microstructure on the brittle crack initiation and arrest ability was explained from two aspects: (1) the critical event of crack initiation at low temperatures, and (2) the hindering effect of HAGB on the propagation of brittle cracks.

“…The decrease in grain size can improve the corrosion resistance of the alloy. Liu et al [ 22 ] showed that by controlling the rolling temperature of TiZrAlB alloy, one can regulate the phase composition and microstructure of the alloy. The results revealed that the alloys prepared, in different heat treatment conditions, consisted of single α/α′ phases.…”

A series of Ti‐25Zr‐xY alloys are prepared by a vacuum arc melting furnace. Then, the Ti‐25Zr‐xY alloys are hot‐rolled by a multi‐pass rolling process. The mechanical properties and corrosion behavior of hot‐rolled Ti‐25Zr‐xY alloys were investigated using microscopic characterization. The results show that the microstructure of the alloys is mainly composed of α and α‐Y phases. The particle size of the second phase α‐Y increases with the increase of the Y element. When Y content reaches 0.4%, the alloy exhibits excellent mechanical properties (σ 0.2 = 930 ± 10 MPa, ε f = 10.16 ± 0.3%). The precipitation of the second phase and the presence of metal compounds are responsible for reducing the corrosion resistance of hot‐rolled Ti‐25Zr‐xY alloys. The corrosion behavior of the alloys in chlorine solution is sensitive to the Y content, with Ti‐25Zr‐0.1Y alloy having the best corrosion resistance. The erosion sensitivity of Zr and the precipitation of Y are responsible for the observed pitting corrosion phenomenon.

“…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.
