Experimental study of Bi–Cd–In phase diagram using conventional methods plus quenching and ‘solidification path’ techniques
Bibliographic record
Abstract
The liquidus projection of the Bi–Cd–In ternary alloy system has been redetermined, using the conventional methods of thermal analysis and differential scanning calorimetry, as well as quenching experiments and a ‘solidification path’ technique. In the latter method, specimens were solidified unidirectionally at a very low speed in order to maintain a coherent solid/liquid interface while approximating freezing with complete mixing in the liquid. This produced macroscopic segregation that clearly revealed the phases formed on a scale suitable for straightforward chemical analysis in a scanning electron microscope. Two quasibinary sections were found, one of which (BiIn2–Cd) divides the system into two independent regions. A newly discovered ternary phase, designated Z, as well as several previously unreported ternary four phase reactions of the quasiperitectic type, were observed. The Bi–Z join was found to be a quasibinary peritectic section. A number of solid state reactions of the eutectoid type were also noted.

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.
