- Further information
- This sample was quenched and held at 300 ºC for one hour. It has a Widmanstätten microstructure with the α phase precipitating out of the single β phase during cooling to give α plates in a β matrix. The low temperature at which the transformation takes place leads to less diffusion and results in a finer structure.
