Microstructure Characteristics and Strength–Ductility Mechanisms of a Novel Neutron Shielding Al‐6Mg‐5Gd Alloy Fabricated by Laser Powder Bed Fusion

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Al‐based neutron shielding materials suffer from poor laser powder bed fusion (LPBF) processibility, hindering their simultaneous achievement of good printability and exceptional mechanical properties. In this work, the newly developed rare‐earth Al alloy (i.e., Al‐6Mg‐5Gd) was processed by LPBF technique to meet the printability, mechanical ...

Evading Strength–Ductility Trade‐Off in Titanium Matrix Composites via High‐Critical Resolved Shear Stress Dislocation Promotion and Grain Subdivision

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The strength and ductility trade‐off in titanium matrix composites (TMCs) is a critical factor limiting their widespread application. In this study, a (TiB + TiC)/Ti–6Al–4V composite with an optimal balance between strength and ductility was engineered via multi‐directional forging.
