Effects of substrate miscut on dislocation glide in metamorphic (Al) GaInP buffers

open access: yes, 2013
The effects of miscut toward (111)A of (001) GaAs substrates on α dislocation glide in compositionally step-graded (Al)GaInP buffers grown by metal-organic chemical vapor deposition have been investigated.

Inverse Thermal Softening Behavior in a High‐Entropy Alloy Under Various Strain Rates

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Although face‐centered cubic high‐entropy alloys (HEAs) have received extensive attention and in‐depth research, most existing studies focus on single temperature or strain rate conditions, lacking systematic investigations into deformation mechanisms under extreme thermomechanical coupling environments.

Solute Redistribution Assisted Dual‐Gradient Structure With Superior Strength–Ductility Balance in Mg–Zn–Gd Alloy

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Heterogeneous structures have demonstrated great potential for overcoming the long‐standing strength–ductility trade‐off in metallic materials. In this study, a novel dual‐gradient structure, characterized by gradients in both grain size and precipitate distribution, was successfully constructed in an Mg–2Zn–0.8Gd (wt%) alloy sheet via sliding

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

open access: yesRare 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.

Tailoring the Mechanical Properties of L‐DED‐Fabricated γ‐TiAl Alloys Through Heat Treatment: Correlating Microstructural Evolution With Fracture Mechanisms

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Laser‐directed energy deposition (L‐DED) offers a flexible route for fabricating γ‐TiAl components, but the as‐deposited microstructure requires post‐processing to overcome limited deformation capability. Here, an L‐DED Ti–48Al–2Cr–2Nb alloy was subjected to solution and solution‐aging treatments.

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

open access: yessteel research international, Volume 97, Issue 10, Page 5079-5089, October 2026.
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.

The Effect of Residual Protein and Fiber on Pea Starch Gels

open access: yesStarch - Stärke, Volume 78, Issue 10, October 2026.
The study investigates how residual protein and fiber affect the heating and gelation behavior of pea starch. Small residual amounts influence water binding, swelling power, solubility, and pasting properties, as well as gel strength and syneresis.

Core–Shell UHTCs as a Multiscale Design Paradigm for Extreme Environments

open access: yesInternational Journal of Applied Ceramic Technology, Volume 23, Issue 5, October 2026.
ABSTRACT An integrated perspective on the performance of multiscale core–shell ultra‐high temperature ceramics (UHTCs) developed through a multiphase design strategy is here presented. The manuscript merges insights gained from studies on ZrB2 formulated and processed in the presence of a second transition metal compound based on W, Mo, or Ta ...
