Isothermal Oxidation of SLM fabricated Mo(Si1-xAlx)2-based composite
Bibliographic record
Abstract
Abstract Near full dense C40 hexagonal structured Mo(Si1-xAlx)2-based composite coupons with 7 mm diameter by 7 mm height were prepared by selective laser melting (SLM) of MoSi2-30 wt.% AlSi10Mg powder mixture and subjected to isothermal oxidation. As a reference, MoSi2 bulk sample was prepared by spark plasma sintering (SPS) technique. The quantitative oxidation tests were conducted in dry air atmosphere at 500 °C for 72 and 120 hours with three specimens for each dwell time. The estimated weight change after 120 h oxidation accompanied with the SEM analysis revealed the slow oxidation of the SPS prepared MoSi2 bulk sample without evidence of pesting, however, the formed oxide layer was not protective and contained large cracks and multiple microcracks. The SLM produced sample showed remarkably slower oxidation rate as well as the formation of only a nanoscale oxide layer, highlighting the significant influence on Al additive to enhance MoSi2 oxidation resistance, thus making the developed material promising to be used as heating element.

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.
