Synthesis, Consolidation and Modelling Study of AA2014-TiB<sub>2</sub> Composite Prepared by Powder Metallurgy (P/M) Method
Bibliographic record
Abstract
This Aluminum alloy matrix composite reinforced with TiB 2 particulates with different volume % of TiB 2 (5, 10 and 15) has been successfully synthesized by P/M route. The composite powders were consolidated by cold uniaxial compaction pressure followed by sintering at 590 ̊ C in nitrogen atmosphere. The effect of reinforcement on the densification was studied and reported in terms of the relative density, densification parameter, tensile rupture strength and Vickers hardness of the composite. The above physical and mechanical properties increase with compaction pressure irrespective of TiB 2 content. Scheil cooling and equilibrium calculations were performed using FactSage for qualitative understanding of the microstructural evolution during sintering. The experimental results showed that samples with 5 volume % TiB 2 exhibits optimum densities after sintering and correspondingly highest hardness.

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.
