Abstract
The processing of Titanium Aluminides (TiAls) and Ti64 significantly benefits aerospace applications due to their excellent strength-to-weight ratio. Ti64 is commonly used for turbine disks, while TiAl is utilized for low-pressure blades. Laser Powder Bed Fusion (L-PBF) can facilitate the seamless integration of these materials, where reducing connections is essential for weight savings. However, challenges remain, such as variations in thermal expansion coefficients and the potential for crack formation during L-PBF. This study develops a functional graded material from Ti64 to TNM-B1 in 20 % increments, for the first time using L-PBF without cracks, followed by post-processing to enhance the microstructure.

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 it
