Keane for his generous assistance with the XRD measurements. Dieter Isheim for managing NUCAPT, helpful discussions, and assistance with this project, and Dr. Department of Energy (DOE) Office of Science by Argonne National Laboratory, was supported by the U.S. Use of the APS, an Office of Science User Facility operated for the U.S. DuPont de Nemours & Co., The Dow Chemical Company, and Northwestern University. Portions of this work were performed at the DuPont-Northwestern-Dow Collaborative Access Team (DND-CAT) located at Sector 5 of the Advanced Photon Source (APS). Reconstructing the phase of a field from intensity measurements is an old and ubiquitous challenge, known as the phase retrieval problem 1,2,3.It has found numerous applications spanning from.

The LEAP tomography system was purchased with funding from NSF-MRI Grant DMR-0420532 and with initial funding from ONR-DURIP Grant N00014-0400798, and with funding for upgrades from N00014-0610539, N00014-0910781, and the Initiative for Sustainability and Energy at Northwestern (ISEN) for grants to upgrade the capabilities of NUCAPT. LEAP tomographic measurements are performed at the Northwestern University Center for Atom Probe Tomography (NUCAPT). This research is funded by the Office of Naval Research under grants N0-0361 and N0-0331 (Dr. Stock: Elements of X-Ray Diffraction, 3rd Edition, Prentice Hall, Upper Saddle Rivery, NJ, 2001, pp. Thesis, Northwestern University, 2007.ī.D.

The few Cu precipitates detected in the simulated samples are primarily located on grain boundaries resulting from heterogeneous nucleation. Comparison of measured Cu precipitate radii, number density, and volume fraction with similar measurements from a GMAW sample suggests that the cooling rate in the simulations is faster than in the experimental GMAW sample, resulting in significantly less Cu precipitate nucleation and growth during the cooling part of the weld thermal cycle. The results are compared to Thermo-Calc equilibrium calculations. Dissolution within the HAZ of cementite (Fe 3C) and NbC (F.C.C.) is revealed using synchrotron X-ray diffraction, while dissolution of Cu precipitates is measured employing local electrode atom probe tomography. Simulated heat-affected zone (HAZ) samples are utilized to analyze the microstructures typically obtained after gas metal arc welding (GMAW). An experimental steel with the composition Fe-1.39Cu-2.70Ni-0.58Al-0.48Mn-0.48Si-0.065Nb-0.05C (wt pct) or alternatively Fe-1.43Cu-2.61Ni-1.21Al-0.48Mn-0.98Si-0.039Nb-0.23C (at. pct) has been developed at Northwestern University, which has both high toughness and high strength after quenching and aging treatments.
