Dynamic Phase Transformation Mechanisms in Ti48Al5Nb2Cr0.6Re0.1C Alloy With Heterogeneous Layered Microstructure

Rare Metals, EarlyView.
ABSTRACT Introducing solid‐state phase transformations into the design of heterogeneous structures is considered an effective strategy for simultaneously optimizing both microstructure and mechanical properties. This study investigates the thermodynamic and kinetic mechanisms of the γ → α transformation in Ti48Al5Nb2Cr0.6Re0.1C alloy under different ...

Inhomogeneity of Room‐Temperature Elastocaloric Effects in NiTi Alloys Fabricated by Laser Powder Bed Fusion

Rare Metals, EarlyView.
ABSTRACT NiTi shape memory alloys are among the most promising solid‐state refrigeration materials. In recent years, additive manufacturing methods for producing difficult‐to‐machine NiTi alloys have gained increasing attention from researchers. This work successfully produces NiTi alloys with good superelasticity at room temperature via laser powder ...

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

Rare Metals, EarlyView.
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 ...

Thermohydrogen‐Induced α→β Phase Transition and Interfacial Aggregation: A Diffusion Bonding Mechanism for Ti65 Alloy at Low Temperatures

Rare Metals, EarlyView.
ABSTRACT Diffusion bonding (DB) of near‐α titanium alloys requires high temperatures, which can cause grain coarsening, structural deformations, and degradation of the workpiece's mechanical characteristics. In this study, thermal hydrogen processing (THP) was applied to Ti65, combined with selective magnetron sputtering of a Ti‐Al thin film to promote

Ru‐Ag Dual Atom Sites for Methane Detection Enabling Intelligent Thermal Runaway Warning in Lithium‐Ion Batteries

Rare Metals, EarlyView.
ABSTRACT Early detection of thermal runaway (TR) is essential for lithium‐ion battery (LIB) safety, as unchecked TR risks catastrophic failures in energy storage systems. Gas‐based sensing offers a faster and more direct approach by detecting decomposition products at the molecular level.
