Mechanical Properties of Nanocrystalline Nominally Multilayered Hexagonal Cobalt Electrodeposits
Bibliographic record
Abstract
The microstructure and mechanical properties of electrodeposited nanocrystalline cobalt were investigated and compared to cobalt electrodeposits produced under waveforms that would result in a nominal multilayered material by alternating electrodeposition conditions in the same electrolytic solution. All sample types were of the hexagonal crystal structure and a preferred orientation was prominent with the introduction of nominal multilayers, in which the basal plane preferentially was oriented parallel to the surface of the deposit. Transmission electron microscopy was used to compare the starting microstructure and post-failure microstructure of cobalt electrodeposits. Tensile tests were performed at a strain rate of 5 x 10-4 s-1 and microhardness tests were performed under a 100g load. The average hardness, yield, ultimate tensile and fracture strengths increased when the electrodeposited cobalt followed a nominal multilayered pulse train. Tensile elongation for cobalt electrodeposits with 100 nm nominal layer thicknesses are more than twice that observed for monolithic cobalt.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
