Investigation of the physico-technological features of the hydro-vacuum cleaning process for the high-entropy alloy CoCrFeNiMn produced from industrial ferroalloys
Bibliographic record
Abstract
This study reveals the hydro physical mechanism of hydro-vacuum, shockwave and cavitation-pulsation counter gravity flotational extraction of non-metallic micro inclusions inherent in the liquid high-entropy alloy CoCrFeNiMn (HEA) obtained by an original method of combined induction remelting of low- and carbon-free ferroalloys with an elevated content of target metals. The effectiveness of the hydro-vacuum technology of vertical suction, confuser-convective acceleration, and diffusion-hydro mechanical dispersion of an upward flow of molten metal superheated by 100–150 °C is theoretically substantiated and experimentally proven. It has been established that vortex-like radial twisting of tangentially directed cavitation currents in the thrust-forming high-speed annular flow of water-liquid-metal pulp formed in the process of counter-gravity acceleration, with subsequent asymmetric slamming of the caverns formed in it, is the main conditioning factor for generation of ultra-frequency shock waves of rarefaction and flotational supplanting of relatively light nonmetallic inclusions from atomised drop-liquid particles of HEA. The powder obtained by the proposed method, by its purity 98.7–99.4% and hardness 250–300 HV0.5, is practically identical to similar high-entropy materials synthesis,ed from pure metals. The findings can contribute to stimulating the development of the proposed cost-effective and easily scalable approach to the production and cleaning of HEAs of different systems.

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.
