Material Scientist
About The Position
Leidos is seeking a Materials Scientist to join our team in Albany, OR to conduct research with a multidisciplinary team focused on investigating additively manufactured (AM) Ni-based superalloys for use in high efficiency, fuel flexible gas turbines. The candidate should possess knowledge and practical experience conducting research in processing-microstructure-property relationships for high performance alloys used in gas turbines or similar structural applications. The position will be100% on site, research and development support for the National Energy Technology Laboratory (NETL) Research & Development facility in Albany, OR. Primary Responsibilities: Characterize microstructures using advanced techniques (SEM, XRD, EBSD, TEM). Perform mechanical testing and phase stability studies (i.e., heat treatments) on additively manufactured Ni-based superalloys. Determine failure and deformation mechanisms associated with high temperature application under service environments. Predict phase equilibria, kinetic phase information/compositions as it relates to thermal history and solidification behavior using computational simulation methods (e.g. CALPHAD, Diffusion Simulations, and/or Related Software). Specify additive manufactured build articles and assist with developing testing and characterization plans. Analyze and interpret data generated from research to understand processing-microstructure-property relationships using advanced materials science concepts and robust statistical analysis. Author and/or co-author reports, manuscripts, and articles suitable for peer-review publication. Participate and present research results in company and client meetings and in externally facing settings. The successful candidate will work on local and geographically dispersed teams with other engineers, scientists, technicians, subject matter experts, faculty members, post-doctoral students, and graduate and undergraduate students across DOE National Laboratories, other U.S. government laboratories, universities, industries, and research organizations. The candidate will attend regular and ad hoc meetings and contribute to the development of written reports, journal articles, and presentations on findings and innovative solutions in DOE-sanctioned meetings, scientific conferences, and national committees.
