Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Nickel‐based superalloys (Ni‐based superalloys) have attracted extensive attention in laser additive manufacturing (LAM) due to their capability to directly fabricate complex and high‐performance structural components. However, the rapid melting and solidification inherent to LAM result in intense thermal cycling, which induces high residual ...

Review of the weldability window in explosive welding processes
Journal of Alloys and Metallurgical SystemsExplosive welding is a solid-state joining technique that employs explosive energy to propel the flyer plate into oblique collision with the base plate, forming a metallurgical bond at the interface. The process parameters, such as the loading ratio, the

Dynamic Covalent Polymeric Foams: En Route to a Sustainable Lightness
ChemSusChem, Volume 19, Issue 5, 13 March 2026.Dynamic covalent polymer foams (DCPFs) combine lightweight cellular structures with adaptive polymer networks, enabling self‐healing, reprocessability, and recyclability. By integrating reversible covalent bonds into foam architectures, these materials open new pathways toward sustainable porous polymers within a circular materials economy.
