“…Through the high‐temperature α‐to‐β allotropic transition, solid solution, and precipitation during cooling, the novel two‐scale network structured DRTMCs were constructed for the first time in 2016. [ 66a,d,81 ] The two‐scale microstructure consisted of the first‐scale network (≈150 µm) with micro‐TiB reinforcement and secondary‐scale network (≈10 µm) with nano‐Ti 5 Si 3 reinforcement ( Figure a). From Figure 11b, when TA15 alloy was used as matrix, the (Ti, Zr) 5 Si 3 silicide particles with a diameter of tens of nanometers were generated after sintering.…”

Discontinuously reinforced titanium matrix composites (DRTMCs), as one of the most important metal matrix composites (MMCs), are expected to exhibit high strength, elastic modulus, high‐temperature endurability, wear resistance, isotropic property, and formability. Recent innovative research shows that tailoring the reinforcement network distribution totally differently from the conventional homogeneous distribution can not only improve the strengthening effect but also resolve the dilemma of DRTMCs with poor tensile ductility. Based on the network architecture, multiscale architecture, for example, two‐scale network and laminate‐network microstructure can further inspire superior strength, creep, and oxidation resistance at elevated temperatures. Herein, the most recent developments, which include the design, fabrication, microstructure, high‐temperature performance, strengthening mechanisms, and future research opportunities for DRTMCs with multiscale architecture, are captured. In this regard, the service temperature can be increased by 200 °C, and the creep rupture time by 59‐fold compared with those of conventional titanium alloys, which can meet the urgent demands of lightweight nickel‐based structural materials and potentially replace nickel base superalloys at 600–800 °C to reduce weight by 45%. In fact, multiscale architecture design strategy will also favorably open a new era in the research of extensive metallic materials for improved performances.

“…1,6) Most studies conducted the solution treatment of TiMo-based alloys in the ¢ phase field, but few studies were devoted to investigating the heat treatment (HT) effect within the ¡/¢ dual-phase field. The studies of Cardoso et al, 1) Jiao et al 27) and Lu et al 28) involved HT within the ¡/¢ zone but were not focused on the HT parameter-structure-mechanical property relationships of the TiMo system in a systematic way. The primary purpose of the present study was therefore to investigate the effect of HT within the ¡/¢ dual-phase field on the structure and tensile properties of a series of binary TiMo alloys.…”

The present study investigated the effect of heat treatment within the alpha (¡)/beta (¢) dual-phase field on the structure and tensile properties of Ti(1.59.5) mass% Mo alloys. The alloys were prepared using an arc-melting vacuum-pressure type casting system. The cast alloys were heat-treated at 700, 750 and 800°C in vacuum for 30 minutes followed by quenching in ice water. The X-ray diffraction (XRD) results indicated that beta (¢) phase intensities increased while ¡/alpha prime (¡A) intensities decreased with increased heat treatment temperature (HTT) and Mo concentration. The ¢ phase was observed to dominate the 800°C-treated Ti9.5Mo alloy, while the highest alpha double prime (¡AA) phase content was observed in the 800°C-treated Ti7.5Mo alloy. Both optical and scanning electron microscopy indicated that a relatively coarse ¡ platelet was always observed in Ti1.5Mo. A fine, uniformly-distributed acicular microstructure was observed in Ti7.5Mo, while an equi-axed ¢ granular microstructure was clearly seen in Ti9.5Mo. The tensile properties were found sensitive to the HTT and Mo concentration. When heat-treated at 700°C, the yield strength (YS) and ultimate tensile strength (UTS) increased while the elongation generally decreased with Mo concentration. The highest YS and UTS were found in Ti7.5Mo and Ti9.5Mo. When heat-treated at 750°C, the strength of Ti5.5Mo was improved without reducing elongation. With Mo concentration increased to 7.5% or higher, the elongation further increased while the strength maintained a similar level. When treated at 800°C, the YS of Ti3.5Mo, Ti5.5Mo and Ti7.5Mo maintained a lower level than Ti1.5Mo and Ti9.5Mo. A fully satisfactory interpretation for the tensile properties and their relationships to the complicated microstructures might not be a simple task due to several different factors simultaneously involved, yet practically it is interesting to note that selected alloys heat-treated within the dual-phase field demonstrated quite promising overall mechanical properties.
