Dr. Chuang Deng, P.Eng.

Research

Area

Metal metallurgy; Nanostructures; Structure defects; Grain boundaries; Metallic glasses; High entropy alloys.

Expertise

Materials Modeling and Simulation.

Research description

I use multiscale simulation tools to investigate the processing-structure-property relationship in metallic materials.

Graduate Student Opportunities

Dr. Deng is currently seeking graduate students. He currently has openings for two Ph.D. students with financial support at the University of Manitoba for Summer (May or July) or Fall (September) 2024 intake. (1) Position 1 will focus on the structure, thermodynamics and/or kinetics of grain boundaries in metals; (2) Position 2 will focus on the design and characterization of high-entropy steels. Both positions will use atomistic simulations and machine learning as the main tools.

Candidates with strong interests and background in materials science or physics are encouraged to contact Dr. Deng (Chuang.Deng@umanitoba.ca) directly. Please include your CV, transcript(s), and indicate your interested area of research in the inquiry.
