3D ion maps reconstructed from APT data for Y, Y-O and Hf-O core-cluster ions in a ODS Fe-14Cr alloy containing Hf.
3D ion maps from HT9 alloy Fe ion irradiated to 10dpa at 470oC. 2.0 at% Ni isosurfaces highlighting Ni segregation to the high and low angle grain boundaries and dislocation lines present in the analised volume.

Variations in hardness of the 17-4PH with heat treatment time at 480 °C and 590 °C.
Atom maps of 17-4PH heat treated for 20 min at 590 °C.Atom maps of 17-4PH heat treated for 24 h at 590 °C.

Direct observation of trapped isotopic hydrogen within a ferritic steel containing vanadium-carbide. As can be seen from the top-down and side slices, heavy hydrogen atoms (2H) are correlated to the carbide positions.
