Welcome to the Leijun Li group in Department of Chemical and Materials Engineering at the University of Alberta! Our group conducts award-winning research in physical metallurgy, welding metallurgy, and additive manufacturing of alloys.

Latest Paper: We recently published a paper "Dissolution of Nb(C,N) and (Ti,V)N in the Coarse-Grained Heat-Affected Zone of Electric Resistance Welded X65 Line Pipe" in Metallurgical and Materials Transactions A. A link for free share is here, and the title page is shown on the right. We found the differences in dissolution behavior of carbides and nitrides during rapid welding thermal cycles. Nitrides were much more stabler and slower to dissolve, and they might have prevented severe austenite grain growth; carbides, on the other hand, were readily dissolvable, and dissolved carbon and alloying elements in austenite might have enhanced the quench-type solid-state transformations for bainite, for example.

Latest News: We celebrate three recent PhD defenses - Zhe Lyu, Tailin Ren, and Ravi Kopparthi successfully defended their PhD theses. Congratulations to the newly minted Dr. Lyu, Dr. Ren, and Dr. Ravi!
