Abstract
The present work reports experimental studies on self-propagating high-temperature synthesis of titanium aluminides. Powder mixture of different Ti:Al atomic ratios were adopted and pressed to make compacts. The compacts were heated up to the ignition temperature from one end using induction heating, giving rise to self-sustaining reaction along the compacts. The propagation of reaction front was monitored using a color CCD camera. X-ray Diffraction analyses showed that the main products constituents were TiAl, Ti3Al and TiAl3 in the case of Ti:Al atomic ratios of 1:1, 3:1, and 1:3, respectively; rapid preheating to temperatures close to ignition temperature resulted in minimization of the occurrence of undesired phases. The effects of various parameters such as the green compact density and titanium particle size on the ignition time, combustion wave velocity, and combustion temperature were studied.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
