Interest in the rheology forming technology for fabrication of light weight materials and for
resolving environmental issues has been growing in industrial and academic society. In this study,
the helical shape stirrer was designed to produce rheological material. The experimental variables,
which were stirring time 0-1200 sec, stirring velocity 0-100 rpm and melt temperatures for semisolid
states, were established. The rheological materials were produced under established
experiment conditions, and then mechanical properties were measured. Sequence-production
equipments were appended to fabrication system of rheology material to make rheology materials
continuously. Therefore, the development of sequence-production system equipped with a specially
designed mechanical stirrer in spiral shape was necessary for fabricating fine grains and their
uniform globular rheology materials. The thixoforging was experimented with rheological A6061
wrought aluminum alloy fabricated by the spiral shape stirrer. Microstructural morphology of the
forged samples was investigated and their mechanical properties characterized.
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.
