Over many decades, significant efforts have been made to improve the strength-elongation
product of advanced high strength steels (AHSSs) by creating tailored multi-phase …

Steels with medium manganese (Mn) content (3∼ 12 wt-%) have emerged as a new alloy
class and received considerable attention during the last decade. The microstructure and …

A novel strategy through controlling the selection of martensitic variant in metallic materials
is proposed to break through the trade-off between strength and ductility. Here we prepared …

Reverted austenite is a metastable phase that can be used in maraging steels to increase
ductility via transformation-induced plasticity or TRIP effect. In the present study, 18Ni …

SA508Gr. 4 N steel is commonly used in nuclear pressure vessels. The current study
discloses the impact of austenitizing temperature on its martensitic transformation. Various …

The kinetics and element partitioning during austenite (γ) reversion from lath martensite in
Fe-2Mn-1.5 Si-0.3 C (mass%) alloy have been investigated. Two different types of γ in terms …

A medium-Mn steel (Fe-12Mn-3Al-0.05 C wt%) was designed using Thermo-Calc®
simulations to balance the fraction and stacking fault energy of reverted austenite …

Abstract The martensitic hot-rolled 0.3 C-6Mn-1.5 Si (wt%) steel was annealed at 630° C for
24 h to improve its cold rollability, followed by cold rolling and annealing at 670° C for 10 …

Ultrafast heating (UFH) at the rates of 10–300° C/s was employed as a new strategy to
anneal a cold-rolled 7wt% Mn steel, followed by the immediate cooling. Severely deformed …

The effects of cementite (θ) and retained austenite (RA) on the kinetics and microstructure
evolution in austenite (γ) reversion of an Fe-2Mn-1.5 Si-0.3 C (mass%) alloy have been …
