Abstract

fetched live from OpenAlex

An application of semisolid processing to magnesium alloys is described, emphasizing both the fundamental aspects and up-to-date successful industrial applications. The key advantages of the semisolid route are discussed, including longer tool life, tighter dimensional tolerances and better process consistency. The particular attention is paid to reduced temperature of semisolid processing, providing common benefits for magnesium alloys due to their high affinity to oxygen, requiring an expensive protection and leading otherwise to ignition and burning. Major microstructural factors controlling properties of magnesium alloys after semisolid processing are considered. It is concluded that although the reduced temperature results in higher part integrity, it does not create beneficial microstructural characteristics converting to substantially improved mechanical properties.

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.
