In‐Situ Construction of Multi‐Scale Heterogeneous Structures in L‐DED IN718 Coatings via WMoTaNb Incorporation for Enhanced Strength‐Toughness Synergy

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT To improve the strength–toughness balance of IN718, and alleviate the brittleness commonly associated with refractory high‐entropy alloys, this study proposes a novel strategy to fabricate defect‐free IN718/WMoTaNb heterogeneous multiprincipal element alloy coatings via laser‐directed energy deposition.

Co‐Optimization of Mechanical Performance and Osseointegration of Titanium‐Based Composites via a Novel Microwave‐Driven Boronization Strategy

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT The use of Ti6Al4V alloy in dental implantation is constrained by its high elastic modulus and biological inertness, which lead to delayed osseointegration and a high failure risk. Additionally, its chemical incompatibility with hydroxyapatite (HA) impedes the development of stable bioactive composites.

Synthesis of Dual Phase High Entropy Ultra‐High Temperature Ceramics From Different Carbon Sources

International Journal of Applied Ceramic Technology, Volume 23, Issue 5, October 2026.
ABSTRACT Dual phase (Hf,Nb,Ta,Ti,Zr)C‐(Hf,Nb,Ta,Ti,Zr)B2 ceramics were synthesized by boro‐carbothermal reduction of oxides with different carbon black powders. The starting materials reacted differently based on the particle size, surface area, and additives in the carbon powder.

Unveiling Entropy‐Driven Hard‐Tough Synergy Mechanisms in High‐Entropy Carbonitride Ceramics

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT High‐entropy ceramics manifested promise for extreme environments, yet their phase stability and mechanical synergy mechanisms remain elusive. Herein, entropy‐difference carbonitrides, including (TaTiV)CN, (TaTiVNb)CN, and (TaTiVNbHf)CN, were designed and consolidated via spark plasma sintering.

Effect of Cu element on morphology of TiB2 particles in TiB2/Al−Cu composites

Transactions of Nonferrous Metals Society of China, 2020
Abstract In order to explore the influence of Cu element on the morphology evolution of the in-situ TiB2 particles, the 10 wt.% TiB2 reinforced Al−5wt.%Cu based composite was prepared by mixed salt casting. The morphology characterization and transformation of TiB2 reinforcements caused by Cu element were investigated by multi-scale microstructure ...

The Influence of NiB2 on the Microstructural Evolution, Mechanical, Tribological, and Electrochemical Corrosion Performance of Spark Plasma Sintered TiAl Composites

Engineering Reports, Volume 8, Issue 8, August 2026.
Gamma titanium aluminide (γ‐TiAl) alloys are attractive lightweight materials for high‐temperature structural applications. However, their limited wear resistance and susceptibility to localized corrosion restrict wider deployment. Ceramic reinforcement offers a potential route to performance enhancement, but the combined tribological and ...
