- •
Precipitates in the V–4Cr–4Ti alloy are Ti-(CN) with NaCl structure.
- •
The Ti-rich precipitates are platelet-like in three dimensional space.
- •
Twins occur in both ends of the precipitates and the midst of these is twin-free.
- •
Twinning and its elimination is explained by displacive followed by diffusion.
