A numerical-experimental investigation on the deposition of Ti-45Nb on mild still using automated laser fabrication process
Bibliographic record
Abstract
Automated Laser Fabrication process (Laser Cladding) has shown tremendous potential for various applications such as rapid prototyping, coating, and production of functionality graded parts. Parallel to other technical challenges involved in this method, exploring different materials and alloys with novel properties that can be adopted for the fabrication process using ALFa is another priority for the research in this field. Ti-45Nb is an attractive alloy because of its low modulus of elasticity, high corrosion resistance, significantly increased threshold oxygen pressure for ignition (from that of pure Titanium) and superior biocompatibility. In this paper, different aspects of the deposition of premixed powder Ti-45Nb on mild still are studied. To gain better insight into the nature of the deposition of this alloy, a 3D time-dependent numerical model is developed in which all material properties are considered to be temperature-dependent. The model is used to correlate the microstructure and the phases formed at different processing parameters with the interaction time between the laser beam and the powder or in turn the heating and the cooling rates during the process.

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.
