Real-time observation of alpha nucleation in Ti-6Al-4V [VIDEO ABSTRACT] 

This video was captured during an in-situ heating stage SEM experiment using a secondary electron camera at the University of Manchester, UK. The Ti-6Al-4V sample was heated to 1000°C to the full β-phase field and then slowly cooled (0.3°C/s) through the β transus, and the α-phase nucleation was recorded by the contrast change in the secondary electron camera from topography development on the sample surface due to surface relief. Microscope operated by Dr Alec E Davis and Dr Jack Donoghue, sample preparation by Nick Byres. These results were published in an Acta Materialia paper in 2021:
