The traditional extrusion and thixo-extrusion processes of wrought magnesium alloy were
studied with both computer numerical simulation and experimental methods. The thixo-extrusion
set-up was made. The constitutive model of semi-solid AZ61 alloy was established in our prior
literature. The comparison of two forming processes had been done. Results indicated that smaller
load and uniform strain & stress were acquired in thixo-extrusion process. Simulation results were in
good agreement with experimental ones.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
