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.

Atom Probe Group

02 Oct 2017

Three PhD students join the Atom Probe group


Megan Carter, James Famelton and Charles Fletcher joined the Atom Probe group to start their respective PhD research projects

We are welcoming three new PhD students in the Atom Probe group:

Megan Carter (Lincoln College), working on Linking Microstructure to Neutron Irradiation Defects in Advanced Manufacture of Steels.

James Famelton (Corpus Christi College), working on Investigating the Initial Cluster Formation Mechanisms in High-Strength 6XXX Aluminium Alloys by Atom Probe Tomography.

Charles Fletcher (Oriel College), working on Enhancing 3D Atom probe Imaging for Nano-Electronic Devices.

The three of them will be under the supervision of Michael Moody.

A warm welcome to you all!
