Abstract

fetched live from OpenAlex

Laser cladding process causes thermal stresses, which lead to the appearance of residual stresses and substrate distortions. In the present study, laser cladding was applied to a 5052 aluminium alloy using a cw Nd:YAG laser and coaxial injection of Al–50Si powders. Residual stresses were quantified by X-ray diffraction and by sample strain measurements. The differences in the results obtained by these two methods highlighted the influence of the heat affected zone (HAZ). A model of three strain domains has explained these differences: the coating, the HAZ and the substrate. Experiments identified an optimal treatment speed, leading to maximum compression stresses. Moreover, at a certain fixed speed, thermal stresses balanced each other in the sample leaving the substrate undistorted.

Not 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.
