“…This is attributed to that the higher heat‐treatment temperature (900 °C) with longer cooling time for HT900 allows extended eutectoid reaction between Ti and Cu. [ 46,47 ] The existence of Ti 2 Cu phase is confirmed by the EDS analysis in Figure 4e,f, where the content of Cu element in point 3 and in point 6 is 35.5 wt% and 33.5 wt%, respectively.…”

This work investigates the corrosion behavior and mechanism of laser powder bed fusion produced (LPBFed) Ti5Cu and its heat‐treated counterparts in 3.5 wt% NaCl solution. The results indicate that heat treatment can enhance the corrosion resistance of LPBFed Ti5Cu by generating Ti2Cu phase, and heat treatment at higher temperature enhances corrosion resistance by forming a stable oxide film with a lower electron diffusion rate. The existence of Ti2Cu phase in the heat‐treated sample acts as the microanode that decelerates the corrosion on α‐Ti phase (prior dissolution of Ti2Cu phase). The long‐term immersion test results also confirm that the Ti2Cu phase present in HT900 (at higher heat‐treatment temperature) provides a better protective effect against corrosion compared to the one in HT740 and as‐LPBFed samples. Compared with the heat‐treated counterparts, the worst corrosion resistance of the as‐LPBFed Ti5Cu is attributed to that the acidic environment (e.g., Cl−) increases the electron diffusion rate in the film/solution interface, which makes the thermodynamically unstable α'‐Ti phase be preferentially corroded.

Titanium (Ti) alloys are widely used in frontier fields like aerospace and biomedical engineering. Laser additive manufacturing (LAM), as an innovative technology, is the key driver for the development of Ti alloys. Despite the significant advancements in LAM of Ti alloys, there remain challenges that need further research and development efforts. To recap the potential of LAM high-performance Ti alloy, this article systematically reviews LAM Ti alloys with up-to-date information on process, materials, and properties. Several feasible solutions to advance LAM Ti alloys were reviewed, including intelligent process parameters optimization, LAM process innovation with auxiliary fields and novel Ti alloys customization for LAM. The auxiliary energy fields (e.g., thermal, acoustic, mechanical deformation and magnetic fields) that can be applied during LAM Ti alloys affect the melt pool dynamics and solidification behaviour, altering microstructures and mechanical performances. Different kinds of novel Ti alloys customized for LAM, like peritectic α-Ti, eutectoid (α+β)-Ti, hybrid (α+β)-Ti, isomorphous β-Ti and eutectic β-Ti alloys are reviewed in detail. Furthermore, machine learning in accelerating the LAM process optimization and new materials development is also outlooked. The review summarizes the material properties and performance envelops and benchmarks the research achievements in LAM of Ti alloys. In addition, the perspectives and further trends in LAM of Ti alloys are also highlighted.
