Elastic and thermodynamic properties of divalent transition metal carbides <i>M</i>C (<i>M</i> = Ti, Zr, Hf, V, Nb, Ta)
Bibliographic record
Abstract
We have investigated the elastic and thermodynamic properties of transition metal carbides (TiC, ZrC, HfC, VC, NbC, and TaC) using the three body force potential model and density functional theory based ab initio approach. The computed second-order elastic constants (C 11 , C 12 , C 44 ) are in close agreement with the available experimental as well as theoretical results. The other related elastic parameters (B 0 , B 0 ′, C S , C L , G, ν, E, A, β, ξ, λ, Cauchy pressure (C 12 – C 44 ), B 0 /G, and E/ρ ratio) have also been computed successfully. The calculated Debye temperatures are in reasonably good agreement with the available data.

How this classification was reachedexpand
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.
