Homogenised at 800 °C, quenched
Applications
Sample preparation
Etched in NH4OH/H202

Further information
This sample was homogenised at 800 °C and quenched rapidly to retain supersaturated metastable b grains. With quenching there is insufficient time for diffusion to occur resulting in a metastable structure.
