Abstract:The effect of initial grain size on the recrystallization behaviour of a type 304 austenitic
stainless steel was investigated using hot torsion. Refinement of the initial grain size to 8 μm had a
considerable effect on the flow curve shapes, peak and critical strains and also on DRX kinetics,
compared with an initial grain size of 35 μm. Microstructural investigations using EBSD suggest a
transition from conventional (discontinuous) to continuous dynamic recrystallization with
decreasing initial grain size. Al… Show more
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.
