“…Moreover, the oxidation damage can be increased by the tensile mean stress induced during non-isothermal loading, which is verified in the investigations [9][10][11][12]. It can be the main reason of that the oxygen content under thermal 180° out-of-phase loading is higher than that under in-phase loading, as shown in Fig.…”

“…Moreover, for the above superalloys, the oxidation damage is also caused [6,8], but it cannot play a dominant role. For some other superalloys [9][10][11][12], the OP TMF loading induces more serious damage compared with the IP TMF loading. The oxidation damage is dominant under OP TMF loading for these superalloys, and the high tensile stress corresponding low temperature can increase the oxidation damage.…”

Abstract. The fatigue damage behavior was experimentally investigated in different axial-torsional thermo-mechanical loading conditions for Ni-based superalloy GH4169. The strain controlled tests were carried out with the same von Mises equivalent mechanical strain amplitude of 0.8% in the temperature range from 360°C to 650°C. The results show that the fatigue life is drastically reduced when the axial mechanical strain and the temperature are in-phase, which can be due to that the creep damage is induced by the tensile stress at high temperature. Moreover, the fatigue life is further decreased when the axial mechanical strain and the shear strain are out-of-phase, which can be attributed to that the non-proportional hardening can increase the creep and the oxidation damages. Furthermore, the tensile stress is crucial to the nucleation of creep cavities at high temperature compared with the shear stress. The tensile and shear stresses all can increase the creep damage under fatigue loading at high temperature. In addition, the oxidation damage can be induced during cyclic loading at high temperature, and it can be increased by the tensile mean stress caused in non-isothermal loading.

“…Oxidation-resistant coatings are mostly used to protect the components from these effects. However, their use is limited because through-thick cracks tend to develop during their formation or at cyclic oxidations as a result of strains mismatch linking the coating material and the substrate alloy material (Prasad et al , 2016; Punnose et al , 2016). For high-temperature applications, one material that preserves its mechanical strength and resistance to surface degradation under high operating temperatures is nickel-based superalloys (Makena et al , 2017).…”

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.
