Abstract
A ceramic material designed for ultra-high temperatures (UHTCs) generally comprised of nitrides, carbides, and borides derived from transition metal elements, with a particular focuson compounds belonging to TaC and Group IVB (Hf and Zr). Hypersonic vehicle nozzles andengine components can take advantage of the unique characteristics of these materials. A broadrange of coatings and composites based on UHTC is currently being developed to conquer theinherent fragility, weak thermal shock resistance, and brittleness of bulk ceramics. Ultra-hightemperature materials with high entropy have gained considerable attention in recent years. Areview of the current state of the art of UHTC composites and coatings will be provided in thisreport. Properties and processing approaches to achieve the microstructure will be discussedfurther.

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
