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.

Goldschmidt Early Career Researcher Poster Prize


Awarded to the poster "Atom probe tomography of Carlin type gold mineralisation", by Dr Phillip Gopon (Department of Earth Science)

The poster "Atom probe tomography of Carlin type gold mineralisation",
authored by P. Gopon, M.A. Auger, L.J. Robb, M.P. Moody and J. Wade

has been awarded a Goldschmidt Early Career Researcher Poster Prize by the Mineralogical Society and the Natural Environment Research Council. This collaboration between University of Oxford researchers from the Department of Earth Science and from the Atom Probe group at the Department of Materials has been selected among those presented in the Goldschmidt session 18d The mineralogy and geochemistry of metal deposits and secondary sources, and their mineral processing, hydrometallurgy and biotechnologies, as part of the Goldschmidt Conference held on 13th-18th August in Paris.

Congratulations!
