Abstract

fetched live from OpenAlex

The influence of the structure of Vacuum Plasma Sprayed (VPS) boron carbide on the elastic modulus of the deposit was studied. Thermal sprayed structures consist of individual splats along with unmelted and partially melted particles, pores, microcracks, and splat boundaries. Thermal sprayed deposits exhibit anisotropic properties parallel and perpendicular to the splat plane. In the present study, micro-indentation hardness tests were performed on the vacuum plasma sprayed B4C to determine the elastic modulus parallel and perpendicular to the coating surface. Nano-indentation hardness tests were also performed on the cross-sectional microstructure to measure the elastic modulus parallel to the coating surface to compare with the values obtained from micro-indentation tests. A developed object oriented finite-element method also was performed to estimate the elastic modulus. The elastic modulus of the as-sprayed structure decreased significantly compared to the conventionally processed B4C materials. Due to an anisotropic microstructure, the perpendicular elastic modulus was lower than that parallel to the spray plane. Numerical simulations using finite element method confirmed anisotropic elastic behavior of the structure and highlighted the effect of splat boundaries on the elastic modulus in the as-sprayed structure.

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.
