Evolution of martensite

A movie of martensitic transformation in Fe-0.18C-0.2Si-0.9Mn-2.9Ni-1.5Cr-0.4Mo wt% steel, using confocal laser microscopy. The time and temperature are indicated on the left hand corner. The contrast arises from the displacements caused by the phase change from austenite to martensite.

The movie has kindly been supplied for educational purposes by Professor Toshihiko Koseki of Tokyo University.



The crystallographic orientation is available.
