Abstract
Al-Mn-Zn ternary system is experimentally investigated at 400°C using diffusion couples and key alloys. Phase relationships and homogeneity ranges are determined for binary and ternary compounds using EPMA, SEM/EDS, and XRD. Reported ternary compound T3 (Al 11 Mn 3 Zn 2 ) is confirmed in this study and is denoted as τ 2 in this paper. Two new ternary compounds ( τ 1 and τ 3 ) are observed in this system at 400°C. τ 1 is determined as a stoichiometric compound with the composition of Al 31 Mn 8 Zn 11 . τ 3 has been found to have homogeneity range of Al x Mn y Zn z (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mi>x</mml:mi><mml:mo>=</mml:mo><mml:mn>9</mml:mn><mml:mtext>–</mml:mtext><mml:mn>13</mml:mn></mml:math> at%; <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M2"><mml:mi>y</mml:mi><mml:mo>=</mml:mo><mml:mn>11</mml:mn><mml:mtext>–</mml:mtext><mml:mn>15</mml:mn></mml:math> at%; <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M3"><mml:mi>z</mml:mi><mml:mo>=</mml:mo><mml:mn>75</mml:mn><mml:mtext>–</mml:mtext><mml:mn>77</mml:mn></mml:math> at%). The binary compounds Al 4 Mn and Al 11 Mn 4 exhibit limited solid solubility of around 6 at% and 4 at% Zn, respectively. Terminal solid solution Al 8 Mn 5 is found to have maximum ternary solubility of about 10 at% Zn. In addition, ternary solubility of Al-rich β -Mn′ at 400°C is determined as 4 at% Zn. Zn-rich β -Mn′′ has a ternary solubility of 3 at% Al. The solubility of Al in Mn 5 Zn 21 is measured as 5 at%. Based on the current experimental results, the isothermal section of Al-Mn-Zn ternary system at 400°C has been constructed.

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 it
