Inhomogeneous deformation in welded high density polyethylene
Bibliographic record
Abstract
Abstract The effect of the thermal history on the properties of welded high density polyethylene is studied. The lamellar microstructure observed in the weld is different from that in the bulk slow cooled material. The weld has lower crystallinity and smaller lamellar size, both of which change with annealing. The differences in the microstructure between the weld and the surrounding material produce differences in the plastic properties. The low ductility of the welded samples is a direct result of the relatively low yield stress within the weld. Annealing of the weld can improve the tensile properties, but in quenched welds the final properties are still inferior to the bulk material. Displacement controlled, constant velocity microindentation tests are shown to provide a rapid means of evaluating the properties of the weld. © 2002 Wiley Periodicals, Inc.

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.
