Additive Manufacturing of Hot Work Tool Steel by Laser Powder Bed Fusion Utilizing Powder Mixtures Including Grinding Chips: Assessing Chemical Homogeneity and Achievable Hardness

Advanced Engineering Materials, Volume 28, Issue 1, January 2026.
Grinding chips of high‐alloyed steel are prepared to be admixed to a starting powder mixture for laser powder bed fusion. A three‐stage preparation is performed, including washing in acetone, magnetic separation, and ball milling. The addition of 30% of grinding chips to the powder mixture allows the fabrication of dense samples.

Additive Manufacturing of Negative Thermal Expansion Metamaterials Using Steels

Advanced Materials Technologies, Volume 11, Issue 1, 8 January 2026.
Architected lattices with tunable negative thermal expansion are fabricated from common steels using laser powder bed fusion metal additive manufacturing. Optimized multimaterial interfaces and geometry‐driven design produce robust, defect‐minimized structures that remain dimensionally stable up to 300 °C, enabling scalable solutions for thermal ...

Design and Development of a Magnetic Lead Screw With a Quasi‐Halbach Array

IET Science, Measurement &Technology, Volume 20, Issue 1, January/December 2026.
This paper reports on a study of a novel MLS with a quasi‐Halbach array and a rotor made of a SMC. The proposed topology has an array formed from a helix of discretized pieces of PMs axially and radially magnetized in its slider. Using FEA and static magnetic simulations, prototypes were assessed.

A Computational Fluid Dynamics Investigation of Midshaft Reducing Gas Composition Impacts on Blast Furnace Performance

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
The feasibility of shaft‐level reducing gas injection has been widely investigated as a method to increase operational efficiency, enable higher oxygen‐enrichment operation, and minimize process CO2 emissions. Computational fluid dynamics modeling is employed in this study to investigate the impacts of shaft injection gas composition on replacement ...

Stability and the United States ‐ What Are We Doing? A Historical Summary of Financial Support for Steel Structural Stability Research

ce/papers, Volume 8, Issue 6, Page 25-30, December 2025.
Abstract Since the early 1900s, supporters of steel structural stability research in the United States have consisted of a broad cross‐section of public, private, and nonprofit entities, with federal and state governments financing most of the activity. However, the model for future government support of science and engineering research in the U.S.

Studying the Impact of Impurities on the Performance of Cadmium‐Free all Sputtered CIGS Solar Cells Using Titanium–Tungsten Barrier

Solar RRL, Volume 9, Issue 23, December 2025.
The study demonstrates that a titanium/tungsten barrier layer significantly improves Cu(In, Ga)Se2 (CIGS) solar cell performance by effectively screening the impurities from steel substrate to CIGS layer. Increasing the barrier layer thickness from 0 to 208 nm boosts efficiency from ≈4% to 16% due to improvement in open circuit voltage and fill factor,

Investigation of Oxide Dispersion Strengthening Effect on the Strength of Diffusion‐Bonded AISI304 Parts

Advanced Engineering Materials, Volume 27, Issue 21, November 2025.
Experiments for reinforcing the diffusion bonding plane by the oxide dispersion strengthening effect are presented. Small ceramic particles (0.5 and 50 μm, respectively) are incorporated. Furthermore, ceramic particles help to penetrate stable passivation layers, enabling atomic diffusion across bonding planes. Since a ceramic–metallic interface cannot
