Abstract

fetched live from OpenAlex

Abstract Since the invention of spray forming by Prof. Singer in the early 80's, many researchers have attempted to explain the rapid solidification features of the spray deposit through mathematical modelling of the process. The break‐up of the stream into atomized drops followed by the deposition of these semi‐solid droplets into a rotating deposit have been simulated using both the energy and the momentum equations. These models, however, do not explain the fineness of structure observed in spray formed products when compared to cast structures of similar dimensions and experiencing similar cooling rates. A single fluid technique provides an ideal tool to study the effect of atomization variables on the structure evolution of a spray formed deposit. It will be shown based on Cu‐6Sn, Al‐Cu and Al‐Fe alloys that the undercooling of second and subsequent phases in the deposit accounts for the rapid solidified structure in spray forming.

Full frame distilled prediction

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.
