Job Description

We have an opening for a Postdoctoral Researcher to conduct experimental research focusing on embrittlement, corrosion, and oxidation of refractory metal alloys. You will actively participate in research to evaluate material degradation during brazing and welding processes using a variety of thermo-mechanical testing techniques, including but not limited tensile, torsion, lap-shear testing, TGA, dilatometry. You will operate in multi-disciplinary research setting with other staff engineers, material scientists, and technicians to design experiments, conduct research, and analyze results. Research will be expected to disseminate research finding with internal colleagues and external academic/scientific community through peer-reviewed publications and conference presentations. This position is in the Materials Engineering Division (MED) of the Engineering Directorate.

In this role you will 

  • Conduct research in the area of brazing and welding processes.
  • Design, implement, and analyze experiments to assess and characterize embrittlement, corrosion, and oxidation of refractory metal alloys.
  • Contribute to and actively participate in the conception and execution of research to address defined problems.
  • Publish research results in peer-reviewed scientific or technical journals and present results at external conferences seminars and/or technical meetings.
  • Collaborate with others in a multidisciplinary team environment both at LLNL and in other national laboratories and universities to accomplish research goals.
  • Pursue independent (but complementary) research interests and interact with a broad spectrum of engineers and scientists internally and externally to the Laboratory.
  • Perform other duties as assigned.

Qualifications

  • Ability to secure and maintain a U.S. DOE Q-level security clearance which requires U.S. citizenship.
  • PhD in Material Science and Engineering, Mechanical Engineering, Chemical Engineering, or related fields.
  • Experience with material characterization, including but not limited to thermo-mechanical analysis of metals, metal alloys, or ceramics (DSC, TGA, DTA, dilatometry).
  • Experience with metallographic characterization techniques, including but not limited to SEM, EBSD, texture/grain analysis.
  • Experience with evaluating structure-property-process relationships of metal alloys or ceramics.

Qualifications We Desire

  • Familiarity with brazing, reactive sintering.
  • Experience or familiarity with material degradation during brazing, soldering, or welding processes, such as liquid metal embrittlement or corrosion.
  • Experience with non-destructive evaluation techniques, such as resonant ultrasound spectroscopy, pulse-echo, and eddy current measurements.

Additional Information

All your information will be kept confidential according to EEO guidelines.

Position Information

This is a Postdoctoral appointment with the possibility of extension to a maximum of three years.  Eligible candidates are those who have been awarded a PhD at time of hire date.
