Effects of compaction technique on processing response of aluminium PM alloys
Bibliographic record
Abstract
The objective of this research was to assess the effects of compaction method (uni-axial die compaction and cold isostatic pressing) on two aluminium powder metallurgy alloys. Both systems were mixtures of elemental and master alloy powders. Mechanical and physical properties from samples prepared using both methods were compared. Analyses included the measurement of green and sintered densities, tensile properties and microstructural analyses. Results indicated that sintered products of a largely comparable quality could be realised for both alloys regardless of the compaction approach employed. PM2324 displayed sensitivity to compaction pressure such that low values were preferred for cold isostatic pressing (CIP) whereas higher values yielded superior sintered products when die compaction was implemented. Conversely, compaction pressure had no meaningful impact on the sintering behaviour of PM7075 for CIP or die pressed samples.

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.
