Opportunity Description

Title of Research Opportunity: Nanocrystalline Powder Development The Materials Division of the U.S. Army Research Lab is seeking a materials science fellow, performing professional engineering research on a wide variety of projects; studies center on the development of bulk nanostructured metals using scalable powder metallurgy methods. The research opportunity focuses on large volume powder fabrication utilizing high-energy mechanical mills, and processing and development of bulk parts from powdered precursors. The researcher will be responsible for conducting aspects of independent research, as well as providing support for current and ongoing group efforts on nanostructured metals and alloys. This includes, but is not limited to, the synthesis, processing, and development of various metallic powders to control particle shape, size, distribution, and microstructure, both in the starting powders as well as in the fabricated parts. Efforts will involve the data collection, analysis, and documentation of the material’s microstructural evolution during processing and or bulk consolidation and use of experimental, analytical, and characterization methods such as optical and electron microscopy techniques, e.g., differential interference contrast, SEM-EDS, TEM-EELS; thermal techniques, e.g., TGA/DTA/DSC; structural techniques, e.g., XRD; and mechanical property measurements, e.g., microhardness and tension/compression. Additional support will be required for the chemical characterization of the as-synthesized powders and consolidated bulk parts for trace elemental analysis for oxygen, sulfur, nitrogen, or carbon. Incumbent will be also using standard powder manufacturing practices such as sintering, HIPing, FAST, and extrusion processing to form the bulk parts. The researcher should possess rudimentary familiarity and skills with machine tools to prepare mechanical testing samples for small-scale and miniaturized mechanical testing schemes including those in tension, compression, shear, hardness, creep, wear, and fatigue. At times, the research will require the incumbent to produce written summaries of test results and or of data analysis and interpretation. Keywords: Nanocrystalline

About Us

Grooming future leaders in science and technology requires enhancing the skills, knowledge and experience of workers early in their careers. To that end, ORAU (Oak Ridge Associated Universities) assists in connecting the best and most diverse students, recent graduates, faculty and professionals with world-class fellowships, internships and jobs, whether in national laboratories, research institutions, federal government offices or private sector R&D departments.

ORAU works with agencies such as the U.S. Army Research Laboratory (ARL) Research Associateship Program (RAP) allow Postdoctoral Fellows, Journeyman Fellows (undergraduate and graduates students and recent graduates), Senior Researchers, and Summer Faculty engage in research initiatives of their own choice, that are compatible with the interests of the government and will potentially contribute to the general effort of the ARL. We work with the Environmental Protection Agency (EPA) to place recent graduates in full-time and part-time jobs in the Office of Research and Development at EPA under the National Student Services Contract. ORAU also works with Center for Medicare and Medicaid Innovation.

Research opportunities include, but are not limited to the following disciplines: Aerospace Engineering, Anthropology, Archeology, Biology, Biochemistry, Biological Engineering, Biomechanical Engineering, Biomedical Engineering, Chemical Engineering, Chemistry, Computer Science, Computer Engineering, Data Science, Electrical Engineering, Environmental Health Risk Assessment, Environmental Science, Entomology, Epidemiology, Ergonomics, Geology, Health Education Mechanical Engineering, Materials Science, Mathematics, Nanotechnology, Photonics, Physics, Public Health Economics, Public Health Policy, Toxicology, and more.
