Microstructure and first hydrogenation properties of Ti30V60M10 + 4 wt% Zr (M=Fe, Co, and Ni)
Bibliographic record
Abstract
The hydrogenation properties of Ti 30 V 60 M 10 (M = Fe, Co, and Ni) + 4 wt% Zr alloys at room temperature were investigated. The alloys were tested in their as-cast state and after being heat treated at 300 °C under a dynamic vacuum for 2 h. All as-cast alloys presented a two-phase microstructure consisting of a BCC matrix and a C14 secondary bright phase rich in Zr and M atoms. The BCC structure transformed into a face-centred cubic (FCC) main phase upon hydrogenation, while the C14 phase also hydrogenate but kept its structure. The as-cast alloys showed slow hydrogen absorption initially, but heat treatment reduced incubation times and improved hydrogenation kinetics for all compositions. • Investigated hydrogenation properties of Ti 30 V 60 M 10 (M = Fe, Co, and Ni) alloys with 4 wt% Zr at room temperature. • As-Cast alloys presented a two-phase microstructure of BCC matrix and C14 bright phase. • Heat treatment at 300 °C before activation reduced incubation times and improved hydrogenation kinetics. • Hydrogenation transformed the BCC structure to FCC, while the C14 phase also hydrogenate but kept its structure. • After heat treatment, Ti 30 V 60 Ni 10 alloy showed the most significant enhancement in hydrogenation kinetics.

How this classification was reachedexpand
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.
