High performance Ni-based alloys are required for use in exhaust valve applications in the next generation, high efficiency automotive engines. These alloys are expected to be as low as possible in cost while being able to perform at temperatures up to 950°C in an exhaust gas environment. The work will highlight the use of transmission electron microscopy, atom probe tomography, USAXS, and phase field modeling in understanding microstructural evolution in a model Ni-Fe-Cr alloy. *Research sponsored by the U.S.DOE, Assistant Secretary for Energy Efficiency and Renewable Energy, Office of Vehicle Technologies, under contract DE-AC05-00OR22725 with UT-Battelle, LLC. This work used resources of the Advanced Photon Source, a U. S. DOE Office of Science User Facility operated for the DOE Office of Science by Argonne National Laboratory under Contract No. DE-AC02-06CH11357. Atom Probe Tomography was conducted at the Center for Nanophase Materials Sciences, a DOE Office of Science User Facility.
