Rare Metals, Volume 45, Issue 11 (published November 1), features a paper by the team of Gu Dongdong at Nanjing University of Aeronautics and Astronautics (NUAA). Using 93W alloy (93W-4.9Ni-2.1Fe) as a model, nano- and micron-sized Ni-Fe powders were ball-milled with W powder to design a "mixed-scale powder": the nanoparticles enhance laser absorption through multiple reflections in the powder bed and promote melting of high-melting-point W particles and microstructural refinement, while the microparticles ensure powder flowability and spreading quality, enabling high-quality LPBF forming of tungsten alloy parts: average grain size refined to 4.90 μm, surface roughness Sa reduced to 7.56 μm, compressive strength 2534.2 MPa, and compressive strain 34.1%. This strategy is transferable to other refractory metal systems. (Special case of a paper published on Nov 1; inclusion confirmed by Ada.)
