Hierarchical Strengthening Design in AlCrCuFeNi2.5/CuCrZr Composites Enables Strength–Ductility–Conductivity Synergy

Rare Metals, EarlyView.
ABSTRACT Developing Cu‐based composites that simultaneously achieve ultra‐high strength, ductility, and electrical conductivity remains critical for advanced electrical contact applications. In this work, multiphase AlCrCuFeNi2.5 high‐entropy alloy (HEA) reinforcements are incorporated into CuCrZr matrix via spark plasma sintering (SPS) and annealing ...

Collaborative Sampling and Imaging of Phytoplankton Communities by Two Long‐Range Autonomous Underwater Vehicles Using Acoustic Tracking and Messaging

Journal of Field Robotics, EarlyView.
ABSTRACT Collaborative operation of multiple autonomous underwater vehicles (AUVs) can effectively achieve scientific goals that are hard to achieve by independently operated vehicles. Some science payloads are large, expensive, and need to be installed in the vehicle's nose cone. A vehicle can only carry one such payload.

Investigation of the impact of grain boundary hydrogen concentration on hydrogen embrittlement sensitivity of polycrystalline Fe: Molecular dynamics insights

Smart Molecules, EarlyView.
Molecular dynamics simulations were utilized to explore the influence of grain boundary hydrogen concentration on the hydrogen embrittlement sensitivity of polycrystalline iron. This graphical abstract visualizes the corresponding microstructural evolutions, with results demonstrating that elevated hydrogen concentration reduces the yield and ultimate ...

A Comparative Study of Directed Energy Deposition‐Arc and Casting: Enhancing Mechanical and Thermal Properties of Hot‐Work Tool Steels

steel research international, EarlyView.
The study investigates the influence of DED‐Arc/M versus casting on the microstructure and material properties of X40CrMoV5‐1 (AISI H13) hot‐work tool steel. DED‐Arc/M yields finer microstructures, superior mechanical strength, and ductility, but slightly reduced thermal conductivity.

Substitution of Ti by Nb in Maraging Steel: Effects on Strengthening Mechanisms and Crystallographic Behavior

steel research international, EarlyView.
This work demonstrates that replacing Ti with Nb in maraging steel forms nanoscale Nb–Mo particles along boundaries, strengthening the alloy without relying on Ti phases. Heat‐treatment tuning promotes uniform crystal orientation and balanced grain boundaries, enabling strong yet ductile behavior.
