The objective of this project is to incorporate microstructural aging into the creep and uncertainty quantification (DFT focus), accelerate the design and development of cost-effective high-performance advanced structural materials such as high entropy alloys, Ni- and Fe-based alloys for extreme environments (e.g. high temperature, high stress, oxidation, and/or corrosion) using multiscale computational modeling and machine learning. The research will focus on perform DFT calculations on interfacial energy with and without segregants of C, B and N, perform mean-field precipitation kinetics of sigma phase formation and growth in 347H stainless steels, and develop machine learning algorithms and then construct ROM for sigma phase precipitation kinetics in 347H stainless steels. This opportunity involves collaboration among national laboratories of Department of Energy, universities, and industries. 

Required Qualifications:

  • Ph.D. degree in Physics, Chemistry, Materials Science, Chemical or Mechanical Engineering, or a related field.
  • Substantial DFT expertise in calculating crystal defect energetics such as interfaces, solid understanding of diffusion in alloys.
  • Demonstrated proficiency in DFT calculations on diffusion, phonon, and mechanical properties using VASP.
  • Demonstrated proficiency in computer programming and code development using Python, C/C++, Fortran, Linux script, parallel computing, etc. 
  • Excellent oral and written communication skills. 
  • Excellent record of peer-reviewed quality publications.

Preferred Qualifications:

  • Experience in supervised and unsupervised machine learning.
  • Experience with data mining of CALPHAD generated data using TC-Python interface.
  • Ability to work independently and with minimum supervision.
  • Ability to work effectively as a part of a team in a multi-disciplinary environment and interact with people with a variety of expertise.
