Abstract Scope |
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. This talk will present results from our work on the early stages of gamma’ evolution in a model Ni-Fe-Cr alloy. The work will highlight the use of transmission electron microscopy, atom probe tomography and phase field modeling in understanding microstructural evolution in this 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. Atom probe tomography was conducted at the Center for Nanophase Materials Sciences, which is a DOE Office of Science User facility. |
