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 available at low cost while being able to perform at temperatures up to 950°C in an exhaust gas environment. This talk will present our experiences in the computational design of alloys that would have the potential to meet these challenges. The use of advanced characterization techniques including atom probe tomography in the validation of alloy design will be highlighted. *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. |
