- Microstructure of CP Ti, ASTM F 67, Grade 4 (UNS R50700) (longitudinal plane, specimen was annealed at 704 °C) prepared using the three-step method and etched with Kroll’s reagent to reveal the grain structure.
- Microstructure of CP Ti, ASTM F 67, Grade 2 (UNS R50400; specimen was in the as-rolled condition) prepared using the three-step method and viewed with polarized light to reveal the grain structure. Note the mechanical twins in the grains (arrows).
- Microstructure of CP Ti, ASTM F 67, Grade 2 (UNS R50400; specimen in the as-rolled condition) prepared using the three-step method, followed by a vibratory polish, and viewed with crossed polarized light to reveal the grain structure. Note the deformation twins (arrows).
