Nanjing Chenguang Equipment Tender Opens: BLT Leads with 8.97M Yuan Bid; Farsoon and Leiming Laser Shortlisted

2026-08-13 · Impact score: 32

The bid evaluation results for the 'Molding Equipment' project at Nanjing Chenguang Group have been announced: Xi'an Bright Laser Technologies (BLT) is the top bidder candidate at 8.97 million yuan, with Farsoon Technologies (12.7 million yuan) and Tianjin Leiming Laser (10.4998 million yuan) also shortlisted. Per the tender requirements, the equipment must be delivered to the site by September 20. Nanjing Chenguang Group, a subsidiary of China Aerospace Science and Industry Corporation (CASIC), specializes in aerospace equipment manufacturing; this procurement is part of its metal additive manufacturing capacity expansion. Military enterprises are steadily advancing their metal 3D printing equipment acquisitions, and the installation of new systems directly drives demand for titanium alloy and superalloy powders, representing a key entry point for powder suppliers into the defense supply chain. For powder buyers, the key takeaways are: ① Military equipment procurement is typically followed by powder tenders—watch for Nanjing Chenguang's upcoming powder procurement announcements. ② As BLT and Farsoon expand their installed equipment base, their associated powder qualification systems offer a practical route for powder producers to enter the military market. ③ Military customers impose strict requirements on powder batch traceability and quality management systems, so suppliers should assess certification and qualification costs in advance.

Materials & Design: Internal Oxidation Route in LP-DED Produces ODS-Type 316L Y Stainless Steel with 774 MPa Room-Temperature Strength

A study published in Materials & Design demonstrates the fabrication of yttrium-alloyed 316L stainless steel (316LY) via laser powder directed energy deposition (LP-DED) using an internal oxidation pathway, eliminating the need for mechanical alloying or thermal consolidation steps. The as-deposited material achieves a relative density exceeding 99%, a room-temperature ultimate tensile strength of 774 MPa, and an elongation of up to 67% after aging treatment. This route offers a new additive manufacturing paradigm for producing oxide dispersion strengthened (ODS) steels. ODS steels are key candidate materials for radiation-resistant applications such as nuclear energy, but conventional powder metallurgy routes are complex and costly. If successfully scaled, the additive manufacturing approach could significantly lower production barriers. Value for powder buyers: (1) ODS-type powders such as yttrium-alloyed 316L are high-value specialty powders, with custom demand from nuclear energy customers—companies capable of producing specialty alloy powders can tap into this market; (2) the process imposes stringent requirements on the distribution control of oxide dispersoids in the powder, making mixed powder quality control a key supply factor; (3) in the short term, this remains at the laboratory stage, so it is advisable to track subsequent irradiation performance validation and pilot-scale scale-up progress.

SUSTech Publishes in Nature Communications: Entropy Engineering Strategy Yields Medium-Entropy Alloys with >99.99% Relative Density in LPBF

In a study published in Nature Communications on August 13, researchers from the Department of Mechanical and Energy Engineering at Southern University of Science and Technology (SUSTech) demonstrated that mixing CoCrNi and 316L powders, combined with an entropy engineering strategy, enables temporal control of entropy during the LPBF process. This approach produced near-pore-free medium-entropy alloys with relative density exceeding 99.99%. Mechanistically, configurational entropy increases during printing alongside microstructural evolution, optimizing melt pool spreading and thermal history. The result is a stable microstructure dominated by sub-grains with low geometrically necessary dislocation density, yielding superior fatigue resistance and corrosion performance compared to conventional powder bed fusion–processed medium- and high-entropy alloys. Medium- and high-entropy alloys represent a frontier material direction in metal additive manufacturing. This study shows that high-performance medium-entropy alloys can be achieved by blending standard powder grades, offering a new low-cost material pathway. Value for powder buyers: (1) The blended-powder route reduces reliance on customized pre-alloyed medium-entropy powders, potentially increasing demand for conventional CoCrNi and 316L grades. (2) Powder producers may explore service models that combine 'proportional blending with process coupling,' offering customers mixed-powder solutions and process packages. (3) As this is currently at the fundamental research stage, it is advisable to monitor subsequent scale-up validation and engineering application cases.

National Innovation Center for Robotics Proposes ILRPBF Process: Heat-Treatment-Free Titanium Alloy Printing with High Strength and Ductility

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.
