Dynamic Compression Characteristics of Zr_(50.5)Cu_(36.5)Ni_4Al_9 Bulk Amorphous Alloy at Cryogenic Temperature
Bibliographic record
Abstract
Zr50.5Cu36.5Ni4Al9 bulk amorphous alloy has been prepared by copper mold casting method.The dynamic compression characteristics and the features of fracture morphology of Zr50.5Cu36.5Ni4Al9 bulk amorphous alloy at room temperature(25℃)and cryogenic temperature(-40 ℃)were investigated with split Hopkinson pressure bar(SHPB)and S-4800 scanning electronic microscope(SEM).The results show that,under the dynamic compression load,the anti-compressive strength decreased with the load increase of Zr50.5 Cu36.5 Ni4 Al9 bulk amorphous alloy.The dynamic anti-compressive strength of Zr50.5Cu36.5Ni4Al9 bulk amorphous alloy has cryogenic temperature sensitivity at-40℃ temperature.The main fracture morphology of the Zr50.5Cu36.5Ni4Al9 bulk amorphous alloy shows the vein patterns with the crack and amorphous alloys melted at room temperature.The main fracture morphology of the Zr50.5Cu36.5Ni4Al9 bulk amorphous alloy shows the herringbone pattern at-40℃ temperatures.

How this classification was reachedexpand
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.
