چکیده
Atom probe tomography has characterised the microstructural changes in T91 steel after BOR60 reactor irradiation at five temperatures between 376 °C and 524 to doses 14.6 dpa 35.1 dpa. Irradiation-induced precipitation segregation carbide/matrix interface induced by neutron been characterised. characterisation shows that Mn, Ni, Si -rich (MNS-rich) clusters form irradiated 415 °C, which is not observed higher 460 °C. The number density, volume fraction composition of MNS-rich have P found segregate carbide matrix lower temperature only

Atom probe tomography of swift ion irradiated multilayers
Nanometer scale layered systems are well suited to investigate atomic transport processes induced by high-energy electronic excitations in materials, through the characterization of the interface transformation. In this study, we used the atom probe technique to determine the distribution of the different elements in a (amorphous-Fe2Tb 5 nm/hcp-Co 3 nm)20 multilayer before and after irradiation...
متن کاملCharacterization of Precipitates with the Atom Probe
The parameters that can be measured from atom probe random area analyses of small spherical precipitates and platelets have been examined with a combination of simulation and geometrical models. The results indicate that the probe aperture should be less than 50% of the diameter of the precipitate in order to reliable measure the true composition in a significant proportion of precipiates.
متن کاملCo-precipitated and collocated carbides and Cu-rich precipitates in a Fe-Cu steel characterized by atom-probe tomography.
The composition of co-precipitated and collocated NbC carbide precipitates, Fe3C iron carbide (cementite), and Cu-rich precipitates are studied experimentally by atom-probe tomography (APT). The Cu-rich precipitates located at a grain boundary (GB) are also studied. The APT results for the carbides are supplemented with computational thermodynamics predictions of composition at thermodynamic eq...

The role of laser assisted atom probe tomography (APT) in microelectronics is discussed on the basis of various illustrations related to SiGe epitaxial layers, bipolar transistors or MOS nano-devices including gate all around (GAA) devices that were carried out at the Groupe de Physique des Matériaux of Rouen (France). 3D maps as provided by APT reveal the atomic-scale distribution of dopants a...
متن کامل3D ChemiSTEMTM Tomography of Nano-scale Precipitates in High Entropy Alloys
Electron tomography is a three-dimensional technique well suited for characterizing fine-scale microstructural features on the order of 10-100 nm. Typically performed in a transmission electron microscope (TEM), it relies on successive image acquisition at multiple sample tilts. Images may be formed through various techniques including conventional and scanning transmission electron microscopy ...
