Leidos is a Fortune 500™ company aimed at embracing and solving some of the world’s most pressing challenges. Through science and technology, Leidos makes the world safer, healthier and more efficient.
Our Civil Group offers an array of exciting career opportunities for the best IT, energy, logistics and engineering professionals.
Leidos is seeking a PhD researcher in Materials Science & Engineering or a similar field to study joining technologies such as welding and solid-state diffusion bonding that are extensively utilized for fabricating and connecting components in various fossil energy systems. Currently NETL-RIC’s Structural Materials Team is performing several tasks/projects that require trials of materials joining in lab scale using capabilities at NETL and Oregon State University. In addition, the team is collaborating with Oak Ridge National Lab and industrial companies such as Vacuum Process Engineering to accomplish these tasks.
Primary Responsibilities & Tasks Include:
- Processing-microstructure-property relationships in nickel-, iron-, and aluminum-based alloys.
- Diffusion bonding of advanced high temperature alloys.
- Laser welding of very thin metal foils.
- Ultrasonic welding of very thin metal foils.
- Friction-stir welding of very thin metal foils.
- Characterizing microstructures of joined regions using advanced techniques (SEM, XRD, EBSD, EPMA, FIB).
- Perform mechanical testing (tensile, fatigue, and creep) of joined (diffusion bonded, welded) specimens of bulk or thin foil materials.
- Experience in writing technical reports, and peer-reviewed journal articles based on their research.
- A minimum of PhD in materials science and engineering, or related areas is required and less than 2 years prior relevant experience.
- Understand processing-microstructure-property relationships in nickel-, iron-, and aluminum-based alloys.
- Knowledge of laser welding of very thin metal foils.
- Knowledge of ultrasonic welding of very thin metal foils.
- Experience performing mechanical testing (tensile, fatigue, and creep) of joined (diffusion bonded, welded) specimens of bulk or thin foil materials.
- Experience characterizing microstructures of joined regions using advanced techniques (SEM, XRD, EBSD, EPMA, FIB).
- Experience Testing High Entropy Alloys.
