Abstract

fetched live from OpenAlex

Fully first-principles calculations have been performed to investigate the alloying effect on the sulphur embrittlement of the n - n ' interface of nickel-based single-crystal superalloys. The shear and cohesive strengths of the inter-face are calculated in terms of Mayer bond orders (BOs), and the ratio R BO of shear strength over cohesive strength is analysed as a function of alloying element substitution. The interface characteristics are also studied using the electron charge-density distribution. It is found that the interplay between shear and cohesive strengths has a significant influence on the interfacial embrittlement. Using the phenomenological theory of fracture as well as the calculated ratio R BO, we propose a new mechanism responsible for relieving sulphur embrittlement of the n - n ' interface through alloying substitution.

Teacher imitation

Not 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.
