Nextel 720/silica composites by metal organic chemical vapor infiltration
Bibliographic record
Abstract
The development of non oxide ceramic matrix composite has resulted in composites with suitable property for certain structural application, but they all retain susceptible to long term degradation after high temperature exposure to oxidizing environments. Continuous oxide fibers reinforced oxide matrix composites are attractive for use as high temperature structural materials because they can combine composite properties with long term oxidative stability. In this paper, the processing of Nextel 720/silica composites by MOCVI (metal organic chemical vapor infiltration) at atmosphere pressure is described. TEOS (Tetraethylorthosilicate) was used as precursor. The effects of concentration of O 2, flux of carrier,temperature of TEOS and deposition temperature on deposition rate of silica and Nextel 720/silica microstructure were studied with lots of experiments. The results exhibit the optimal conditions for MOCVI are TEOS temperature 60℃, deposition temperature 600℃, flow rates of Ar and O 2 400 ml·min -1 and 30 ml·min -1 respectively.

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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
