| Abstract Scope |
Titanium alloys have a complex α-lath morphology. Prior work at CAMM quantifying 2D microstructural features for property-predictive neural networks necessitated a more complete understanding of the morphology. Microstructural feature quantification by stereological methods, and automated image segmentation algorithms depend on either assumptions about or direct observation of the 3D morphology. DualBeam™ FIB/SEM serial sectioning was used in combination with TEM, and OIM techniques to characterize the morphology of α-laths in titanium alloys. Advanced understanding of the morphology will provide insight for property-predictive neural networks, phase-field models, and ultimately phenomenological models. |
