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

This study provides new insights into the influence of grain refinement and crystallographic texture on the passivation behavior and electrochemical response of AA2024 aluminum alloy in phosphate buffer solution (pH 9). A nano-grained (NG, 100–150 nm) microstructure with high-intensity {011} orientations, i.e., Goss {011}<100>, Brass {011}<211>, and P {110}<221 > texture components, was produced through cross accumulative roll bonding (CARB) technique. Electrochemical tests reveal a ~40% reduction in corrosion current density (Icorr) for the NG alloy compared to its coarse-grained (CG) counterpart. Electrochemical impedance spectroscopy (EIS) confirmed this, showing a passive film resistance approximately one order of magnitude higher for the NG material. Consequently, these findings illustrate that the CARB technique concurrently refines grains and develops a favorable texture, synergistically enhancing passivation to provide exceptional corrosion resistance in AA2024 alloy.
