Join us and make YOUR mark on the World!
Are you interested in joining some of the brightest talent in the world to strengthen the United States’ security? Come join Lawrence Livermore National Laboratory (LLNL) where our employees apply their expertise to create solutions for BIG ideas that make our world a better place.
We are committed to a diverse and equitable workforce with an inclusive culture that values and celebrates the diversity of our people, talents, ideas, experiences, and perspectives. This is essential to innovation and creativity for continued success of the Laboratory’s mission.
We have an opening for a Postdoctoral Researcher in metal additive manufacturing (AM) with emphasis on the development and understanding of AM process optimization, alloy design and compositional grading, and thermomechanical response in AM components; critical aspect of the work will be the use of advanced electron microscopy techniques to probe microstructural evolution. You will actively participate with and be an integral member of an interdisciplinary team working on advanced manufacturing science, particularly in the context of understanding microstructural interactions to accelerate qualification of AM components. This position is in the Metallurgy and Advanced Microscopy group of the Materials Science Division.
In this role you will
- Provide knowledge of topics, including laser-matter interaction science, alloy design and alloying effects, fundamental metallurgy such as solidification and phase transformations, and thermomechanical response in metal AM components.
- Evaluate microstructural response during thermomechanical testing, such as tensile, compressive, and dynamic loading, mechanical loading at elevated temperatures, and during heat treatments and other types of post-processing.
- Perform characterization of metal AM components, including optical microscopy and electron microscopy, including as SEM, EBSD, and EDS.
- Design and perform complex experiments; collect and analyze resulting multimodal datasets.
- Collaborate with scientists in a multidisciplinary, cross-functional team environment to accomplish research goals.
- Pursue independent but complementary research interests and interact with a broad spectrum of scientists internally and externally to the Laboratory.
- Document research, publish papers in high-impact peer-reviewed scientific journals, and present results within the DOE community and at conferences.
- Maintain and establish laboratory protocols, including adherence to safety and security protocols.
- Perform other duties as assigned.
- Ph.D. in Material Science, Physics, Chemistry, Mechanical Engineering, Chemical Engineering, or related field.
- Broad experience with materials characterization techniques, including X-ray diffraction and scanning/transmission electron microscopy (SEM, TEM) techniques (backscatter imaging, electron backscatter diffraction (EBSD), energy dispersive spectroscopy (EDS), in situ testing and analysis).
- Experience with mechanical testing, including at elevated temperatures.
- Experience preparing samples for metallographic characterization, including sectioning, cutting, grinding, mechanical polishing, and electrochemical etching or polishing.
- Experience analyzing defects and microstructures in additively manufactured metals.
- Ability as an innovative experimentalist with a broad range of experience in experimental design, techniques, and execution.
- Initiative and interpersonal skills necessary to interact with a diverse set of scientists, engineers, and other technical and administrative staff, with the ability to work independently as well as in multidisciplinary research teams.
- Proficient written and verbal communication skills with demonstrated capabilities in delivering presentations and preparing written reports.
Qualifications We Desire
- Experience with metals processing, including the operation of metal additive manufacturing equipment.
- Experience with focused ion beam (FIB) machining.
- Experience in computer programming for data analysis (e.g., Python, Matlab).
All your information will be kept confidential according to EEO guidelines.
This is a Postdoctoral appointment with the possibility of extension to a maximum of three years, open to those who have been awarded a PhD at time of hire date.
