Is synthesizing a Cu35Co35Ni20Ti5Al5 high-entropy alloy beyond the rules of solid-solution formation?
Bibliographic record
Abstract
In this research, an attempt was made to produce multi-component nanocrystalline Cu35Co35Ni20Ti5Al5 alloy by mechanical alloying. To produce this high-entropy alloy, the primary powders were milled for 40 h and characterized by XRD, SEM, EDS, and DSC analyses. The milling process has reduced the size of the crystallites to the nanometer scale and a nanostructured multicomponent powder with a crystallite size of 29 nm was obtained. According to the XRD patterns and EDS maps of the milled powder for the longest time, aluminum and copper were homogeneously distributed, cobalt had a less homogeneous distribution than these two elements, but nickel and titanium remained in concentrated spots. Finally, thermodynamic calculations were done to clarify the reason for the impossibility of forming a solid solution for the synthesis of the Cu35Co35Ni20Ti5Al5 high-entropy alloy.

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.
