Inspection process of military industrial grade
1. Macroscopic inspection
Crack morphology optical mapping -LRB-accuracy 0.01 mm)
2. Microanalysis
SEM scanning (× 5000 times grain boundary observation)
EDS analysis (heat map of element distribution)
3. Reverse deduction
Material database comparison (143 material characteristic spectra)
Ansys Workbench
4. Report output
Failure Mechanism Dendrogram + process improvement scheme
Case comparison
Type of failure
