“…In aeronautical applications, it is widely used in landing gear modulus, helicopter rotors, wings and loadbearing fuselage components on civil (B787 Dreamliner, Airbus A350) and military aircrafts (Airbus A400M). This alloy is characterized by the versatility of its mechanical properties (high strength, highly hardenable, ductility, low density) based on the post-processing thermal treatment, which makes it attractive as a structural titanium alloy ( Ref 35,90,91).…”

In βTi-alloys, some advances and developments have been reached toward optimizing their mechanical performance and their processability. However, the applications of these alloys via laser powder bed fusion (LPBF) are still under investigation. In this work, the processing of βTi-alloys via LPBF and their properties is reviewed with a focus on six selected metallurgical systems which are expected to be top performance materials in applications in the aeronautical and biomedical contexts. These six systems promise a better mechanical and functional performance considering different in-service environments for medical implants and structural applications. After literature analysis, the applicability of βTi-alloys to be processed via LPBF is then discussed considering the relevant fields of applications.

Additive manufacturing has been considered a suitable process for developing high-performance parts of medical or aerospace industries. The electron beam powder bed fusion process, EB‑PBF, is a powder bed fusion process carried out in a vacuum, in which the parts are melted using a highly focused electron beam. The material class of metastable β‑titanium alloys, and especially Ti‑5Al‑5Mo‑5V‑3Cr, show great potential for use as small and highly complex load-bearing parts. Specimens were additively manufactured with optimised process parameters and different heat treatments used in order to create tailored mechanical properties. These heat-treated specimens were analysed with regard to their microstructure (SEM) and their mechanical strength (tensile testing). Furthermore, in situ tensile tests, using a Deben CT5000 and a YXLON ff35 industrial µ‑CT, were performed and failure‑critical defects were detected, analysed and monitored. Experimental results indicate that, if EB‑PBF-manufactured Ti‑5553 is heat-treated differently, a variety of mechanical properties are possible. Regarding their fracture mechanisms, failure-critical defects can be detected at different stages of the tensile test and defect growth behaviour can be analysed.

“…Different approaches, such as hot isostatic pressing of gas-atomized powder, [9,10] hot or cold pressing followed by sintering of blended elemental powders (BEPM), [11][12][13][14] and novel selective laser melting techniques, are proposed to prepare titanium alloy with specified chemical composition. [15][16][17] Regardless of the methods mentioned previously, materials obtained by PM techniques have high relative density and similar mechanical properties as titanium alloys with an equivalent chemical composition produced by conventional route. [18] Understanding the microstructure and mechanical behavior of b titanium alloys in a wide range of temperatures and strain rates is crucial to developing suitable thermomechanical processing parameters.…”

The hot deformation behavior of Ti-10V-2Fe-3Al alloy obtained by the powder metallurgy (PM) method was investigated. Material for the research was produced by blending of elemental powders followed by uniaxial hot pressing. Thermomechanical tests of Ti-10V-2Fe-3Al compacts were carried out to determinate the stress-strain relationships at the temperature range of 800°C to 1000°C and strain rate between 0.01 and 10 s À1. Based on the dynamic material model (DMM) theory, processing maps at constant strain value were developed using data obtained from hot compression tests. The processing maps were elaborated for the final strain value, which was 0.9, and with flow instability criterion domains applied to it. Two critical regions associated with the flow behavior of the investigated material were revealed. Microstructural changes during hot deformation at various temperatures and strain rates were discussed. The correlation between calculated efficiency of power dissipation, flow instability criterion, and microstructure evolution was determined. The presence of defects was confirmed in regions predicted by the instability maps. The microstructure of the investigated alloy, corresponding to the high efficiency of power dissipation characterized by the occurrence of dynamic recrystallization (DRX) phenomena, was also shown. Additionally, average hardness values in relation to variable process parameters were designated. Based on the conducted studies and analysis, processing windows for Ti-10V-2Fe-3Al alloy compacts were proposed.
