Nearly complete strain-induced phase transformation in cold-rolled pure cobalt

Next Materials
The aim of this study is to investigate the effect of high strain levels, achieved through cold rolling, on the strain-induced phase transformation in cobalt, from the Face-Centred Cubic (FCC) phase to the Hexagonal Close-Packed (HCP) one.

Sulfate‐Directed Silver Dendrites with Enhanced Stability for Ultrasensitive SERS‐Based Therapeutic Drug Monitoring

Advanced Science, EarlyView.
This study presents sulfate‐directed silver dendrites (s‐AgDs) as oxidation‐resistant SERS substrates with long‐term stability, reproducibility, and sub‐picomolar sensitivity. Sulfate ions guide anisotropic growth and protect the surface, enabling improved performance over 7 months under ambient conditions.

Effects of V on the dual-phase heterostructure FeCrNiVx medium-entropy alloys

Journal of Materials Research and Technology
Multi-phase combined morphology improves the performance of medium-entropy alloys (MEAs). The heterogeneous FCC and BCC dual-phase FeCrNiVx MEAs (x = 0, 0.1, 0.2 and 0.3, mole fraction) were designed and prepared to elevate the mechanical properties. The

Phase separation promotes FCC-phase mechanical twinning in AlCoCrFeMo0.05Ni2 high entropy alloy

Journal of Metals, Materials and Minerals
The AlCoCrFeMo0.05Ni2 high entropy alloy (HEA) can remarkably enhance its ductility through high-temperature annealing. Nevertheless, the underlying mechanism remains under explored. Herein, we utilized molecular dynamics simulations (MD) to calculate the generalized stacking fault energy (GSFE) curves and uniaxial tensile behavior.

Transforming Grain‐Boundary Brittle Precipitates to Ductility Pathways in Complex Concentrated Alloy

Advanced Science, EarlyView.
By engineering graded BCC/L12 interfaces, brittle precipitates in a complex concentrated alloy enable sequential deformation, realizing gigapascal strength with >20% elongation to solve the strength‐ductility trade‐off. ABSTRACT Conventional wisdom holds that hard grain‐boundary (GB) precipitates embrittle structural alloys by acting as crack ...

Deformable Eutectic Alloy With Near‐Theoretical Yield Strength via Hierarchical Nanoscale Multiphases and Sessile Defects

Advanced Science, EarlyView.
A CoCrFeNiTa0.4 eutectic high‐entropy alloy achieves a near‐theoretical yield strength of 2.6 GPa with 13.6% plasticity. This breakthrough stems from a hierarchical nanostructure (FCC‐Laves lamellae with L12/D022 precipitates), which alleviates the inter‐phase modulus/hardness mismatch through synergistic strengthening and toughening, guiding the ...

Hierarchical Strain‐Modified Medium‐Entropy Carbide Ceramics Exhibit Exceptional Ablation Resistance up to 2400°C

Advanced Science, EarlyView.
A novel strategy is developed by doping reduced graphene oxide (rGO) into a (HfZrTi)C medium‐entropy ceramic. This induces a hierarchical strain modification mechanism, synergistically inhibiting crack propagation at the microscale and dissipating stress at the mesoscale.
