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 ...

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 ...
