Abstract

fetched live from OpenAlex

Fe–Si–B amorphous alloys with less than 80 at. % Fe are now in practical use because of their excellent magnetic softness and rather high magnetization (Js) basically owing to the lack of intrinsic magnetic anisotropy and the high Fe content, respectively. A strict upper limit of the Fe content (about 80 at. %) for the formation of a single amorphous phase with good magnetic softness hinders the improvement in Js of the Fe-based amorphous alloys. The alloys with the high Fe content exceeding the limit commonly have the as-quenched structure consisting of coarse α-Fe grains in an amorphous matrix, which inevitably results in inferior magnetic softness. The simultaneous addition of proper amounts of P and Cu is found to be significantly effective in decreasing the grain size of α-Fe phase, formed in an amorphous matrix in the as-quenched Fe82Si9B9 amorphous alloys with high Fe content exceeding the limit. Fe-rich Fe81.7Si9B7P2Cu0.3 heteroamorphous alloy with an as-quenched structure consisting of extremely small α-Fe-like clusters of about 3 nm or smaller in diameter, randomly dispersed within the amorphous matrix, exhibits the lower coercivity of 7 A m−1 and the higher Js of 1.56 T than the typical Fe-based monolithic amorphous alloy at an as-quenched state.

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.
