Fabrication of Porous Fe/TiB2 Composites by Reactive Precursor Method
Bibliographic record
Abstract
Porous Fe/TiB2 composites were fabricated by a reactive precursor method. Fundamentally, iron, titanium and boron powders were blended to synthesize 20 to 70vol%TiB2 particles in Fe/TiB2 composites after the combustion reaction. Additionally, various foaming agent powders (CaCO3, MgCO3, SrCO3, TiH2, ZrH2 and C) were added to the blended powder. The blended powder compact was heated to induce the combustion reaction. The specimen prepared with carbon had large pores and high porosity (the maximum porosity was 60% and the pore size was about 800 µm). The reasons why the porosity increases are twofold; (i) the melting point of iron is decreased by carburizing and (ii) carbon is oxidized during the combustion process and the formation of gaseous CO results in generating the pores.

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; a candidate call from one teacher head, not a consensus.
