FEI Quanta 450 FEG SEM equipped with crystal orientation imagine system (OIM) electron backscattered diffraction (EBSD) and energy dispersive spectrometer SDD (EDAX). Spatial resolution 1.0 nm.

 

Microstructure of low carbon steel heated at 10 °C/s to 800 °C and water quenched taken by means of OIM EBSD n Quanta 450 FEG SEM. Image quality map (left, black/white) shows partially dissolved ferrite (bright areas) in a matrix of martensite (dark areas). Inversed pole figure map (right, colour) shows crystallographic orientations of ferrite and martensite.
