Neon field-ion image.

An image with just the Fe2+ ions, showing the absence of iron in
the carbide particle.
An image using the carbon C2+ ions.
Combined image of the C2+ ions superimposed on the field-ion image.
An imaging atom-probe study of a mixed carbide particle in a steel containing titanium and vanadium. Bob wanted to confirm that there is a disturbance in the trajectories of the carbon at the edges of the particle, since the carbon distribution goes beyond the boundaries of the carbide particle. The possibility of such an aberration had been suggested to him by P. Turner.
