“…It is noticed that duplex microstructure models with LM is studied, a lamellae width is adopted as one of the microstructural features. Strain localization complicated by LM during primary hot working of TA15 is addressed in [28], within the numerical framework of a two-scale crystal plasticity model. Mechanism of strain localization is revealed particularly for LM.…”

“…Near‐α titanium alloy Ti–6Al–2Zr–1Mo–1V (TA15) is broadly utilized to create entire parts with asymmetrical geometries for aerospace applications. [ 136 ] Furthermore, the average strength of this composition at both high and room temperatures indicates it is suitable for creating nacelle center beam frames and bulkheads. [ 137 ] Cai et al [ 138 ] developed TA15 components with a good combination of ductility and tensile strength by optimizing AM parameters and subsequent heat treatments.…”

The restricted number of materials available for additive manufacturing (AM) technologies is a determining impediment to AM growing into sectors and providing supply chain relief. AM, in particular, is regarded as a trustworthy manufacturing technology to replace the traditional ones for Ti alloy components. Furthermore, the AM processability of Ti alloys and their features, such as microstructure, texture, and mechanical properties, is strongly dependent on the chemical composition of the processed alloy. It is essential to consider the ultimate applications as well. β Ti alloys are gaining popularity in the biomedical industry, while α + β Ti alloys are increasingly utilized for producing components in the automotive and aerospace sectors. Consequently, the topic has garnered considerable interest, and the current text reviews the advances during the last 10 years in this area to facilitate the pathway from the demanded Ti alloy to the best‐fit AM procedure. While systematically reviewing the works published in the literature, the current text attempts to establish a link between the production method, feedstock type, chemical composition, and the ultimate application. This review also features practical applications of Ti components produced by metal AM methods and offers prospective possibilities and industrial applications.

“…Hot working is the most applicable forming process for the alloys [ 11 ]. Hot forging, a forming technology, improves mechanical properties without sacrificing the complex shape of the components through transforming the coarse heterogeneous microstructure into a fine and homogeneous equiaxial microstructure [ 12 , 13 ]. The forging process plays a great role in the forming of structural titanium alloy components [ 14 ].…”

TC31 is a new type of high-temperature titanium alloy, but few researchers have studied the combination of forming and heat treatment of a component using this material. The component with high ribs and thin webs was studied by numerical simulation and trail production. Based on the establishment of the finite element model, the forming process was analyzed by simulation software, and the maximum forming load of the component was 1920 kN. Ultimately, there were no folding defects of the component during the forming process. The material flow law was revealed by selecting the typical section of the component, and then the forming process was verified and the fully filled component was obtained. After that, the component was subjected to post-processing, and three heat treatment methods were designed to conduct heat treatment experiments on it (heat treatment: solution treatment and aging treatment). By analyzing the influence of three heat treatment methods on mechanical properties, the optimal heat treatment method was obtained, namely a solution treatment at 960 °C for 2.5 h and aging treatment at 610 °C for 7 h. The ultimate tensile strength, yield strength, elongation, and section shrinkage of the component through forging forming and heat treatment are higher than those of original material; meanwhile, it also indicates that the designed heat treatment has a better effect on the high-temperature mechanical properties of this titanium alloy at 650 °C than that at 450 °C. The research on the combination of the forming and heat treatment of this component provides a reference for the engineering application of high-temperature titanium alloys.
