1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Conventional wisdom holds that hard grain-boundary (GB) precipitates embrittle structural alloys by acting as crack initiation sites. In this work, we overturn this paradigm through atomic-scale interfacial engineering, transforming brittle GB phases into ductility pathways in a machine-learning identified model complex concentrated alloy. By precisely tailoring thermomechanical processing, we fabricated compositionally and structurally graded interfaces (GIs) that enable sequential plasticity activation and coordinated deformation across GBs. This interfacial architecture converts an intrinsically brittle multi-phase alloy into a ductile material, achieving an exceptional yield strength of ∼1.2 GPa with a total elongation of ∼20%. The achieved strength-ductility synergy, realized via interfacial plasticity programming, establishes a generalizable materials design strategy to overcome the persistent challenge of GB embrittlement in precipitation-strengthened alloys.
