Pacific Northwest National Laboratory Post Doc Research Associate - Thermomechanical/Friction Stir Processing in RICHLAND, Washington
Organization and Job ID
Job ID: 311397
Directorate: Energy and Environment
Division: Energy Processes & Materials
Group: Applied Materials and Manufacturing
Are you interested in state-of-the-art approaches to metals manufacturing? The Applied Materials and Manufacturing Group at Pacific Northwest National Laboratory is seeking a materials scientist or engineer to support research in friction stir processing of materials. Friction stir processing can be used to modify microstructure in castings and to impart superior material properties locally. This post-doctoral position requires someone who wants to be “hands on” with machinery and develop industrially relevant processes to generate materials with specific microstructure. This assignment will focus on friction stir processing of aluminum and magnesium castings, mainly developing innovative solutions to expand the processing envelop of friction stir processing to enhance mechanical properties. Research will also focus on microstructural characterization such as optical and electron microscopy, and mechanical property testing such as tensile and fatigue to evaluate the processing-structure-property correlation. Applicants should have a strong background in metallurgy and mechanics of materials but should also have some knowledge of thermomechanical processing methods so they can work with engineers to define processing approaches and specify conditions.
The position holder will contribute to the development and application of high performance materials and innovative processing approaches. They will:
Research, plan, design, and conduct experiments involving friction stir processing (e.g., optimizing processing parameters and developing new tool designs)
Collaborate with others to conduct structural characterization (optical microscopy, XRD, SEM, EDS, EBSD, and TEM) and mechanical property evaluation (hardness, tensile, and fatigue).
Interpret the data and correlate it to mechanical properties.
Document the results in reports, compare them with the published literature, and write high-quality peer-reviewed journal publications.
Candidates must have received a PhD within the past five years (60 months) or within the next 8 months from an accredited college or university.
Ph.D. in materials science, materials engineering, metallurgy, mechanical engineering, or related field
Experience in friction stir processing, friction stir welding, surface processing, or other processes involving severe plastic deformation
Expertise in physical and mechanical metallurgy of Al and/or Mg alloys. Familiarity with non-ferrous metal solidification and castings is a bonus.
Experience in characterization techniques such as SEM, EDS, EBSD, XRD, TEM, and differential scanning calorimetry.
Experience in mechanical testing methods such as hardness, tensile and fatigue. Familiarity with various ASTM testing standards is a plus.
Expertise in interpretation and the subsequent analysis of characterization data.
Basic understanding of finite element modeling and commercially available software. Familiarity with SolidWorks software is a bonus.
Strong team player and an ability to conduct independent and inter-dependent research. Ability to provide innovative solutions.
Ability to perform work with the level of quality and timeliness to meet required project and client expectations.
Appropriate analytic, task management, and communication skills (both oral and written) to clearly articulate research objectives and outcomes.
