Influence of Thermo- and HIP Treatments on the Microstructure and Mechanical Properties of IN625 Alloy Parts Produced by Selective Laser Melting: A Comparative Study
Bibliographic record
Abstract
This study provides a summary of the effect of heat and hot isostatic pressing treatments on the microstructure and mechanical properties of IN625 alloy processed by selective laser melting. IN625 metallographic and tensile testing specimens were additively manufactured in four different orientations and then subjected to stress relief, low solution annealing and hot isostatic pressing treatments. The as-built alloy exhibited the highest tensile strength, the lowest ductility and the highest anisotropy of mechanical properties among all the tested specimens. Heat and hot isostatic pressing treatments provided an improvement in ductility and homogeneity, but at the expense of lower strength characteristics. The results of this study provide some indications for improving the mechanical properties of additively manufactured IN625 alloy components.

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.
