Ke An

Distinguished R&D Staff Scientist - VULCAN; Materials and Engineering Science Initiative Lead; and IAP Liaison

Dr. Ke An is a Distinguished R&D Staff Scientist and the Lead Scientist of the VULCAN instrument at the Spallation Neutron Source (SNS). He also serves as the neutron scattering Materials and Engineering Initiative Lead and Industrial Liaison of the industry application program of SNS and HFIR (High Flux Isotope Reactor). Dr. An earned Ph.D. from Virginia Tech in 2003, and since then he works at Oak Ridge National Laboratory.

Research interests and activities are in neutron scattering studies of material systems under temperature, magnet, current, and complex loading, etc.; electrochemical performance, durability, and reliability of energy storage/conversion materials; residual stress; fatigue life prediction of structural materials under complex loading; and scientific instrumentation and scientific software development.

Current research includes residual stress and deformation behavior of structural materials including high entropy alloys, additively manufactured alloys, high strength steel, and lightweight alloys; deformation and structural (phase/twinning) transition magnetic shape memory materials; thermal mechanical integrity of critical engineering materials by high spatial resolution neutron diffraction; synthesis, structure, stability and degradation of energy storage and energy conversion materials.
