Tuning Grain Boundary Carbides via Solute Rare‐Earth Elements to Prevent Intergranular Brittle Fracture

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Carbides strengthen the grain boundaries; nevertheless, excessive carbide precipitates embrittle the grain boundaries of high‐temperature alloys during prolonged service. Here, we provide direct evidence of solute rare‐earth atoms and demonstrate that they can trap vacancies and inhibit interstitial diffusion, restraining carbide precipitation

In Situ Formation of L12‐Al3Ti Precipitates Enabling High Strength and Toughness in Oscillating Laser‐Welded Aluminum Alloy

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT A synergistic strategy combining a Ti interlayer and circular beam oscillation was proposed to improve the laser weldability of 6082‐T6 aluminum alloy. The Ti interlayer suppressed porosity, eliminated columnar grains, and significantly reduced grain size by 67.7% at the weld center. Mechanistically, fine L12‐Al3Ti precipitates clearly showing

Nonequilibrium Precipitation Pathway Enabling Direct δ‐phase Formation and Enhanced Cryogenic Strength–Ductility in an Additively Manufactured Multi‐Principal‐Element Alloy

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Overcoming the strength–ductility trade‐off in face‐centered cubic (FCC) multi‐principal element alloys (MPEAs), particularly at cryogenic temperatures, remains a significant challenge. Here, a laser powder bed fusion (LPBF)–enabled direct aging strategy is employed to modify the precipitation behavior in a Ni53Fe20Cr23Nb4 (at%) alloy.

Manipulating RE‐O Bonds Engineered Thermal/Oxygen Transport Characteristics of Monoclinic‐Prime RETaO4 High‐Entropy Ceramics

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Multifunctional thermal protective ceramic thermal/environmental barrier coatings (T/EBCs) are of great significance for applications of various high‐temperature components, and we propose an effective strategy for designing high‐entropy ceramics (HECs) as T/EBCs for SiC ceramic matrix composites (CMCs), where low thermal expansion ...
