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.

DOI: 10.1016/j.matchar.2020.110845
Abstract: Abstract An ultra-low carbon Cu-rich medium manganese steel has been investigated through intercritical annealing and subsequent quasi-austempering to evade grain boundary embrittlement and enhance the resistance against cracking. The normal tempering treatment after intercritical annealing… read more here.

DOI: 10.2355/isijinternational.isijint-2019-329
Abstract: To reveal the law governing V-Ti precipitation behavior in warm-rolled transformation-induced plasticity (TRIP) steel, two steel samples including 0.072V-0.051Ti steel (Bear-V-Ti steel) and 0.001V-0.001Ti steel (Free-V-Ti steel) are designed. Based on a comparative analysis, the… read more here.

Adjustment of Mechanical Properties of Medium Manganese Steel Produced by Laser Powder Bed Fusion with a Subsequent Heat Treatment
Sign Up to like & getrecommendations! Published in 2021 at "Materials"
DOI: 10.3390/ma14113081
Abstract: Medium manganese steels can exhibit both high strength and ductility due to transformation-induced plasticity (TRIP), caused by metastable retained austenite, which in turn can be adjusted by intercritical annealing. This study addresses the laser additive… read more here.
