The Orientation Dependence of Strain Hardening and Texture Development in an Extruded Magnesium Alloy
Bibliographic record
Abstract
Extruded magnesium alloys showed mechanical anisotropy due to the development of strong crystallographic textures during forming processes. In the present study the strain hardening behavior and texture evolution of an extruded AM30 magnesium alloy were studied in compression using cylindrical samples oriented at angles of 0°, 15°, 30°, 45° and 90° from the extrusion direction (ED). The yield strength decreased with increasing angle up to 45° and then increased at 90° from the ED, while the ultimate compressive strength exhibited a reverse trend. Both hardening capacity and fracture strain first increased from 0° to 45° and then decreased at 90° from the ED. The strain hardening behavior was directly related to the texture change and twinning, which played a key role in accommodating the compressive deformation, as the c -axes in most grains were observed to rotate always towards the anti-compression direction, irrespective of the sample orientation.

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.
