Characterization 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 کاملTHREE DIMENSIONAL ATOM PROBE ANALYSIS OF PRE-PRECIPITATE CLUSTERING IN AN Al-Cu-Mg-Ag ALLOY
Trace element additions in age hardening aluminum alloys often modify precipitation products and kinetics. In the case of Al-Cu alloy, combined addition of trace amount of Mg and Ag leads to precipitation of fine and uniform dispersions of plate-like Ω phase on the {111}Al planes in addition to the θ′ precipitates on the {001}Al planes [1,2]. The Ω phase shows high thermal stability and resista...
متن کاملAtom-probe Analysis of Zircaloy
Zirconium based alloys in the Zircaloy series have been analysed with atom-probe field-ion microscopy. During specimen preparation an anodic layer is formed, containing about 50% oxygen. In preliminary analyses of the matrix al1 the minor elements Fe, Ni, Cr and O were detected, and it appears possible to determine with the atom-probe whether any particular heat treatment causes matrix depletio...
متن کاملElectrochemical behaviour of Alloy 600 tubing in thiosulphate solution
Electrochemical and surface properties of passive films formed on Alloy 600 in a thiosulphate solution were studied. Oxide films formed at various passive potentials contained a bilayer oxide, whose composition changed as a function of the applied potential resulting in a change in the impedance behaviour. Destabilisation of the oxide film at potentials within the passive region was observed, w...
