Hierarchical Twin Networks Enable Exceptional Strength and Fracture Toughness in Titanium

Advanced Science, Volume 13, Issue 46, 17 August 2026.
A commercial‐purity titanium with hierarchical ultrafine twin structures delivers an exceptional combination of fracture toughness (KJIc) of 187 MPa·m1/2 and specific yield strength of 140 MPa·cm3·g−1, in which pre‐engineered high‐density twin boundaries stimulate massive and dislocations to blunt crack tip.

Precipitation‐Modulated Harmonic Architectures Enable Superior Strength–Ductility Synergy from Cryogenic to Elevated Temperatures in Nanostructured Alloys

Advanced Science, Volume 13, Issue 39, 13 July 2026.
Precipitation‐modulated recrystallization enables a programmable bimodal harmonic architecture in a high‐entropy alloy, delivering 1–2 GPa yield strength with >10% ductility from −196 °C to 700 °C. The resulting broad‐temperature robustness arises from the synergy of dual‐mode nanoprecipitation, harmonic core–shell topology, and temperature‐adaptive ...

Synergy of Strength and Plasticity in Extruded VZ91K Magnesium Alloy Achieved by Constructing Bimodal Grain Structure via Suppression of PSN‐DRX

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Bimodal grain structure (BGS) demonstrates significant potential in synergistically optimizing the strength and plasticity of magnesium alloys. Acquiring the desired BGS consequently became a critical challenge. This study took the Mg‐9Gd‐1Zn‐0.5Zr (wt%, VZ91K) alloy as its subject. From the perspective of BGS formation mechanisms, it suggests

Strength–Ductility Balance in Additively Manufactured Laminated Fe‐Cr‐Ni/Fe‐Cr‐Ni‐Cu Alloy Heterostructures

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Fe‐Cr‐Ni‐Cu alloy has been extensively utilized over the past few decades due to its low cost yet high strength. Nevertheless, the poor ductility of this alloy limits its real application in industrial fields. In this study, a soft Fe‐Cr‐Ni alloy was combined with a Fe‐Cr‐Ni‐Cu alloy by laser‐directed energy deposition (LDED) to fabricate the ...

Er/Sc Co‐Doping Enabling Laser‐Powder Bed Fusion Aluminum Alloys With Superior Strength and Uncompromised Toughness

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT High‐strength aluminum (Al) alloys are usually unprintable by laser powder bed fusion (LPBF) due to the severe hot cracking along the columnar grains. Doping elements scandium (Sc) and/or zirconium (Zr) is an effective way to eliminate hot cracks by refining the grain size to nearly nanoscale levels.
