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 ...

Steel Plates Subjected to Localised Blast Loading: Transient Measurements Using Ultra‐High‐Speed Camera Technology

Strain, Volume 61, Issue 6, December 2025.
ABSTRACT In this paper, we chart a path to a method that enables us to extract temporal and spatially varying pressure loading effects on the transient response of steel plates under near‐field blast loading, employing ultra‐high‐speed cameras and DIC to measure the transient deformation field. The study addresses the challenges of obtaining full‐field,

Artificial Intelligence and Nuclear Weapons Proliferation: The Technological Arms Race for (In)visibility

Risk Analysis, Volume 45, Issue 11, Page 3839-3859, November 2025.
ABSTRACT A robust nonproliferation regime has contained the spread of nuclear weapons to just nine states. Yet, emerging and disruptive technologies are reshaping the landscape of nuclear risks, presenting a critical juncture for decision makers. This article lays out the contours of an overlooked but intensifying technological arms race for nuclear ...

Corrosion Behavior of Additively Manufactured Steels: A Comprehensive Review

steel research international, Volume 96, Issue 10, Page 51-79, October 2025.
This review explores the corrosion behavior of various steel types, including austenitic, martensitic, duplex, low‐alloy, and maraging steels, produced via additive manufacturing (AM). It discusses how AM impacts material properties, such as grain structure and the formation of defects like porosity, and highlights the importance of optimizing process ...
