Project Description

High-strength Al alloys are widely used in aerospace, automotive, defense and robotics industries. While third-generation steels may have strength of 2 GPa, the best commercial ultra-high strength Al alloys often have a tensile strength of 200-500 MPa. The goal of the project is to integrate experimental and modeling techniques to manufacturing rare-earth-free Al alloys with tensile strength approaching 1 GPa. Such a challenging goal can potentially be achieved by integrating machine learning and fundamental understanding on materials thermodynamics and mechanics of advanced alloys. We envision that the postdoc fellow will work in a disciplinary area at the intersection of additive manufacturing, materials physics, chemistry, and materials characterization. Collaborations with industrial partners and national labs are anticipated.  

Start Date

January-May 2025

Postdoc Qualifications

The candidate should have background and at least 5 journal publications in some of the following subjects:
Advanced manufacturing of metallic materials (additive manufacturing, sintering etc.)
Mechanical behavior of metallic materials; or mechanics of metallic materials
Microstructure characterizations (TEM, SEM, EBSD)
Physical metallurgy
Thermodynamics or kinetics of materials
