Twin‐Wire In Situ Additive Manufacturing of NiTiNb Eutectic Alloys: Eliminating Unmelted Nb Particles and Tailored Superelasticity

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT A major challenge in fabricating eutectic NiTiNb alloys is the incomplete melting of Nb due to its much higher melting point than the NiTi matrix. In this work, a novel electron‐beam freeform additive manufacturing strategy is developed to eliminate unmelted Nb particles and achieve a fully eutectic structure through independent dual‐wire ...

Dual‐Stage Heat Treatment for Enhanced Hydrogen Storage Properties of Mg−Ni−Y Alloys

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Mg−Ni−Y alloy is considered to be one of the most promising hydrogen storage materials, but its high dehydrogenation energy barrier hinders its practical application. A dual‐stage heat treatment (490°C × 4 h + 550°C × 4 h) is applied to optimize the microstructure and hydrogen storage performance of a vacuum‐melted Mg94Ni3Y3 alloy.
