Atom probe cooling

The colder an atom is and the less energy it has, the more precisely researchers know precipitate size that also greatly impact the superalloy’s creep strength using Atom Probe Tomography. The microstructures, of which a typical atom probe reconstruction is shown in Figure 1, from samples linearly cooled at different cooling rates were examined and compared. The / ´ Experiments were performed inside a home-made ultrahigh-vacuum atom probe chamber with a base pressure of 5 × 10 −10 mbar and a close loop cryostat cooling of the sample to 50 K. The aluminum tip was electrochemically etched from a 0.25-mm-diameter aluminum wire. Indeed, these characteristics influence austenite stability at room temperature after cooling and are therefore at the origin of potential TRIP effects under mechanical loading. Atom probe tomography analyses and Thermo-Calc/DICTRA calculations were used to understand how austenite forms during 1 °C/s heating of a 0.2 wt% C high-formability steel. Atom probe tomography (APT) combined with electron back scatter diffraction and transmission electronic microscopy (TEM) is utilized to characterize the nature of copper precipitation during Atom probe tomography reconstructed three-dimensional images of the experimental steel cooled slowly from full austenite phase at a rate of 0.1 °C/s.

Such heavy wire deformation promotes refinement of the ferrite-cementite lamellar structure and gradual cementite decomposition. In our work, a Local Electrode Atom Probe 3000 (LEAP) was used to characterize the microstructural evolution of pearlitic steel. Teletype for Atom. Great things happen when developers work together—from teaching and sharing knowledge to building better software. Teletype for Atom makes collaborating on code just as easy as it is to code alone, right from your editor. Atom Probe Tomography Library.
