Materials Joining - R&D Associate

Date: Jun 11, 2021

Location: Oak Ridge, TN, US, 37831

Company: Oak Ridge National Laboratory

Requisition Id 5308 


We are seeking an R&D Associate who will focus on research and development in the area of materials joining and allied material manufacturing).  This position resides in the Materials Joining Group in the Materials Structures & Processing Section, Materials Science and Technology Division, Physics Science Directorate at Oak Ridge National Laboratory (ORNL).  


As part of our research team, you will investigate high temperature microstructures and the mechanical properties relationship of weld joints, especially dissimilar metal welds for fossil and nuclear energy applications. In this role, you will refine and apply high-temperature mechanical testing techniques suitable for heterogeneous deformation and failure in these welds, perform advanced microstructure characterization and failure analysis, to gain fundamental understanding of the microstructure-property relations of ferritic steels, stainless steels, nickel based super alloys and dissimilar welds among these material combinations. Generate research reports and peer-reviewed journal papers.


Major Duties/Responsibilities: 

  • Develop experimental techniques to characterize interfacial phenomena associated with dissimilar metal joining
  • Conduct specialized mechanical testing on high temperature creep and creep-fatigue properties of weld
  • Conduct microstructure characterization and mechanical property measurements using various equipment and systems
  • Develop and apply analytical tools to analyze the experimental results (microstructure and properties) to obtain the interfacial properties for joining process development
  • Collaborate with team members to facilitate development of ICWE modeling tools
  • Responsible for presenting and reporting research results and publishing scientific results in peer-reviewed journals in a timely manner
  • Work with others to develop research initiatives and proposals to address the materials joining research needs of DOE and US industry
  • Ensure compliance with environment, safety, health and quality program requirements
  • Maintain strong dedication to the implementation and perpetuation of values and ethics


Basic Qualifications:

  • A PhD degree in Welding Engineering, Materials Science/Engineering, Mechanical Engineering or closely related discipline 
  • A minimum of 2 years of experience after PhD degree in research and development on high-temperature materials welded structures


Preferred Qualifications:

  • Experience with microstructure and high-temperature mechanical properties of highly heterogenous welded structures
  • Extensive experience in microstructure characterization of relevant ferritic alloys with advanced electron microscope and other characterization tools
  • Strong hands-on experience in operating materials joining equipment and mechanical testing of weld joints
  • Solid background on materials science and phase transformations of ferritic alloys, and high temperature experiment mechanics
  • Demonstrated working knowledge and practical background in application of digital image correlation (DIC) or other whole field strain experiment technical for high temperature strain measurement
  • Working knowledge of ThermoCal, Dictra, and/or phase field modeling tools for microstructure and phase transformation modeling and simulation of ferrite alloys
  • Knowledge of neutron and high energy synchrotron experiment for material characterization.
  • An excellent record of productive and creative research demonstrated by publications in peer-reviewed journals
  • Excellent written and oral communication skills
  • Motivated self-starter with the ability to work independently and to participate creatively in collaborative teams across the laboratory 
  • Ability to function well in a fast-paced research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever changing needs
