DOI: 10.1002/srin.201900228
Abstract: By altering the temperature and duration of intercritical annealing (IA), the mechanical stability of retained austenites (RAs) is intentionally regulated in newly designed cold-rolled medium manganese steel of Fe-0.4C-7Mn-3.2Al (in wt%). Consequently, a novel combination… read more here.
