“…In a similar vein, TiBw/TA15 composite fabricated by hot pressing followed by solution and aging treatment at 1,000°C redistributed the primary α along the boundaries and resulted in higher ultimate strength at 600-700°C (Zhang et al , 2017b). This was attributed to the redistributed primary α phase residue, which acts as reinforcement at the boundaries.…”

Purpose This paper aims to present a broad review of near-a titanium alloys for high-temperature applications. Design/methodology/approach Following a brief introduction of titanium (Ti) alloys, this paper considers the near-α group of Ti alloys, which are the most popular high-temperature Ti alloys developed for a high-temperature application, particularly in compressor disc and blades in aero-engines. The paper is relied on literature within the past decade to discuss phase stability and microstructural effect of alloying elements, plastic deformation and reinforcements used in the development of these alloys. Findings The near-a Ti alloys show high potential for high-temperature applications, and many researchers have explored the incorporation of TiC, TiB SiC, Y2O3, La2O3 and Al2O3 reinforcements for improved mechanical properties. Rolling, extrusion, forging and some severe plastic deformation (SPD) techniques, as well as heat treatment methods, have also been explored extensively. There is, however, a paucity of information on SiC, Y2O3 and carbon nanotube reinforcements and their combinations for improved mechanical properties. Information on some SPD techniques such as cyclic extrusion compression, multiaxial compression/forging and repeated corrugation and straightening for this class of alloys is also limited. Originality/value This paper provides a topical, technical insight into developments in near-a Ti alloys using literature from within the past decade. It also outlines the future developments of this class of Ti alloys.

“…To further improve the strength and ductility of DRTMCs at room and high temperature, researchers have done lots of studies on the strengthening of DRTMCs by thermal processing and subsequent heat treatment [15−18]. ZHANG et al [17] pointed out that TiBw/TA15 composites could be strengthened after heat treatment that ultimate tensile strength improved 200 MPa and elongation also increased to 9.9% at 600 °C. Furthermore, QI et al [19] fabricated TiC/TA15 composites by induction melting.…”

“…As for the obvious advantages of the powder metallurgy (PM) method for in situ reaction manufacturing of the TMCs with network microstructures, Zhang et al [14] fabricated TiBw/TA15 composites using the Powder metallurgy (PM) method. The results showed that the strength and plasticity of the composites were improved when compared with those of TA15 titanium alloy.…”

TiBw/TA15 (TA15 alloy reinforced by TiB whiskers) composites with network microstructures were successfully prepared by current-assisted sintering at 1100 °C for 10 min. The influence of the sintering parameters on the microstructures of obtained composites was investigated. The sintering temperature was the main factor affecting the average aspect ratio of TiBw, and the average diameter of TiBw could be controlled for various sintering conditions. Yield strength, ultimate compressive strength, and plastic strain at ambient temperature are 1172.5 MPa, 1818.4 MPa, and 22.4% for the TiBw/TA15 composites, respectively. Moreover, yield strength of the composites at 600 °C is 616.3 MPa, which is 26.1% higher than that of the TA15 titanium alloy. The effect of the TiBw on the microstructure evolution for the alloy matrix was discussed in detail. The strengthening mechanism of the TiBw/TA15 composites with network microstructure was attributed to the microstructure modification induced by TiBw, load bearing effect, and dislocation strengthening effect of the TiBw.
