Nature Catalysis, Published online: 22 May 2026; doi:10.1038/s41929-026-01544-5 Pt-based alloys are among the most active catalysts for fuel cells, but strategies to improve their performance are still needed. Now a series of non-metal-modified Pt-based compositionally complex alloys is prepared via a general solvothermal approach and tested for the oxygen reduction reaction, where PtCuNiCoN is s…

There are several good reasons gold is one of the most valuable metals on Earth....

For the first time, researchers at Oak Ridge National Laboratory have used additive manufacturing to fabricate the canisters for powder metallurgical hot isostatic pressing (PM-HIP), eliminating the welding, machining and forming steps that have long constrained the production of large, critical metal components. The developments opens a faster, more flexible path to dense, near-final-shape parts…

dc.title: Review on Atomization of Metals dc.description.abstract: The atomization of liquid metals is a critical technique for producing fine, high-quality metal powders used across various industries, including additive manufacturing (AM), powder metallurgy, and thermal spraying. The process allows for precise control over particle size, morphology, and chemical purity, properties that directly…

German hypercar manufacturer Apollo Automobil has unveiled the Dragon Skin exhaust for its track-only EVO hypercar, a fully 3D printed, single-piece titanium system produced using laser powder bed fusion and aerospace-grade TA15 alloy. Taking 123 hours to print, it is claimed to be the largest one-piece additively manufactured exhaust ever produced, and represents a component…

A team at the University of Hong Kong has developed a new “super steel” that can survive the harsh conditions needed to make green hydrogen from seawater. The material uses an unexpected double-protection mechanism that resists corrosion far better than conventional stainless steel. Even more impressive, it could replace costly titanium parts used in today’s hydrogen systems.

The discovery could help make electronics faster and more energy efficient. Researchers at the University of Minnesota Twin Cities have found a new way to change how a metal behaves electronically by controlling atomic-level interactions at the boundary where two materials meet. The study, published in Nature Communications, shows that interfacial polarization can shift the [...]

dc.title: Microstructure and Mechanical Properties of Bulk EB-PBF Fabricated Gamma-TiAl: Post-HIP and Heat Treatment Effects dc.description.abstract: Gamma Titanium aluminide (TiAl) is widely used in aerospace and defense for its high strength-to-weight ratio and creep resistance. GE implemented gamma-TiAl in their GEnx engine turbine, which significantly reduced fuel consumption, noise, and NOx …

dc.title: Effects of Machine-To-Machine Variability on the Tensile Behavior of L-PBF Ti-6Al-4V dc.description.abstract: As additive manufacturing (AM) techniques are more frequently adopted for the fabrication of parts in load bearing applications, the understanding of the reproducibility of parts is important for the acceptance of AM by industries. Similar machines having different serial number…

dc.title: Predicting LPBF Ti-6Al-4V Microstructure via Multi-Modal In-Situ Process Monitoring dc.description.abstract: Accelerating qualification of laser powder bed fusion (LPBF) components for serial production requires innovative approaches beyond extensive empirical testing. In-situ process monitoring (ISPM) offers a powerful means to detect and characterize process deviations in realtime, pr…

Abstract: The seminar explores the relationship between microstructure, deformation mechanisms, and mechanical behavior in a wide range of metallic systems. It covers dislocation motion, stacking faults, twinning, and defect evolution in magnesium alloys, nickel–aluminum–bronze, pipeline steels, and additively manufactured materials. A multiscale, multimodal characterization approach is used to d…

Laser powder bed fusion (LPBF) enables rapid fabrication of 316L stainless steel (SS 316L) with complex structures, but its rapid solidification and layer-by-layer deposition inevitably induce defects, such as pores and lack of fusion (LOF), severely restricting fatigue performance. This mechanics-focused mini-review summarizes recent research on the fatigue performance of SS 316L, focusing on th…

This article described the investigation of the failed superheater tube made of SA210 Grade C used in a biomass power plant. Visual inspection, microstructural examination, chemical analysis and hardness measurement were employed to analyze the causes of the superheater tube failure. Results from the investigation showed that the major cause of this failure was mainly related to the long-term ove…

Incoloy Alloy 800 is utilized in the Outlet manifold bottom header (OMBH) inside the primary reformer at a fertilizer plant. OMBH was serviced at high temperatures and pressures for ten years in this work. Solution annealing and normalizing method were conducted to improve weldability Incoloy alloy 800. The analysis was carried out by the series of tests, including dye penetrant testing, XRF test…

dc.title: Beyond the Solid Raft: Geometric Strategies to Prevent Build Plate Bowing In CuCrZr L-PBF dc.description.abstract: Build plate bowing in Laser Powder Bed Fusion (L-PBF) presents a major challenge when printing copper and its alloys, due to their high reflectivity and thermal conductivity. These conditions often cause dimensional inaccuracies and degrade structural properties—especially …
