Ke An

Materials and Engineering Science Initiative Lead and IAP Liaison, Senior Neutron Scattering Scientist - VULCAN

Dr. Ke An is a Senior Staff and the Lead Scientist of the VULCAN instrument at 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. Dr. An is specialized on the application of neutron scattering in materials science and engineering including residual stress, deformation mechanism, phase transformation, and texture, etc. His current research focuses on structure of energy storage and conversion materials and deformation behavior in functional and engineering materials by using the advanced neutron scattering technique. 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 additively manufactured alloys, high strength steel, 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.
