This study used SiCp, SiCw, B4C, and GPLs as reinforcements for Ti750 matrix alloy and composites synthesized by spark plasma sintering. The oxidation performances of the composites were then evaluated at 800 °C. 5 vol.% SiCp reinforced Ti750 composite recorded the least oxidation weight gain of 3.80 mg.cm−2, about 41.8% of the base alloy. The average oxidation rates K + of the five materials at 800 °C were less than 1 g.m−2.h−1, indicating all materials were within the anti-oxidation grade with excellent anti-oxidation performance. The oxidation products of the samples contained TiO2, Al2O3, and SiO2. 5 vol.% SiCp reinforced Ti750 composite had significantly flatter and denser oxide film, which was well bonded with the matrix thus having a better protective effect than the matrix material. With the addition of SiCp, the thickness of the oxide film decreased, and the resistance of the material significantly improved its high-temperature oxidation performance.

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.
