In August 2026, the National Innovation Center for Robotics introduced an in-situ interlayer laser remelting (ILRPBF) process strategy that enables in-situ control of Ti-6Al-4V microstructure during laser powder bed fusion (LPBF). The related paper was published in the International Journal of Refractory Metals and Hard Materials. Experimental data show that Ti-6Al-4V samples produced with this process maintained a tensile strength of 1447.0 ± 10.2 MPa while ductility significantly improved to 11.30 ± 0.28%, and surface roughness (Sa) decreased from 11.1 μm to 6.1 μm. The process leverages the rapid thermal cycling characteristics of the laser to achieve microstructure control during printing, eliminating the need for post-heat-treatment steps. Conventionally, LPBF-fabricated titanium alloys exhibit an acicular martensitic structure that offers high strength but low ductility, typically requiring subsequent heat treatment to improve the strength-ductility balance. This heat-treatment-free process has the potential to shorten lead times and reduce energy consumption, offering a new processing route for titanium alloy components. Value for powder buyers: ① If the heat-treatment-free titanium process gains traction, it will increase the demand for Ti-6Al-4V powder in time-sensitive applications such as medical devices and robotics. ② The process imposes stringent requirements on powder oxygen content and batch consistency, giving suppliers with high-quality TC4 powder capabilities a better chance of entering this supply chain. ③ Currently at the laboratory stage, it is advisable to monitor equipment-side implementation and industrialization validation progress.
