Maintaining Grain Boundary Segregation-Induced Strengthening Effect in Extremely Fine Nanograined Metals.
Article in Nano letters, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
Reinforcing grain boundaries through solute segregation is a promising strategy to strengthen nanograined metals. However, maintaining strengthening in extremely fine nanograined metals poses challenges due to grain size reduction and grain boundary structural changes from excessive segregation. This study employs hybrid Monte Carlo/Molecular Dynamics simulations to investigate the interplay between solute concentration, grain boundary structure, deformation mechanism, and strength in Zr-segregated nanograined Cu. Results exhibit significant strength enhancement by optimizing segregation, extending the strengthening effect to a grain size as small as 3.75 nm. Continuous Zr segregation induces a progressive transition from original grain boundaries to segregated and ultimately amorphous grain boundaries. Amorphization alters the dominant deformation mechanism from grain boundary migration to homogeneous shear-transformation-zone activation, fostering and optimizing the strengthening effect in extremely fine nanograined Cu. These findings inspire a novel approach of segregation-induced grain boundary amorphization to leverage strong boundaries and extremely fine nanograins for strengthening nanograined metals.
