Formation of Austenite During Intercritical Annealing of Dual-Phase Steels
Metallurgical Transactions A, 1981The formation of austenite during intercritical annealing at temperatures between 740 and 900 °C was studied in a series of 1.5 pct manganese steels containing 0.06 to 0.20 pct carbon and with a ferrite-pearlite starting microstructure, typical of most dual-phase steels.

Development of textures during rapid intercritical annealing of deep drawing steels
Materials Science and Technology, 1989Abstract It is still possible to optimise the newly developed continuous annealing process for sheet steel production with respect to the properties of the product. In the present contribution, the development of the texture under continuous annealing conditions (very rapid heating, short annealing time, and high annealing temperatures of intercritical

Formation of austenite from a ferrite-pearlite microstructure during intercritical annealing
Journal of Materials Science, 1985The formation of austenite from a coarse grained ferrite-pearlite microstructure during intercritical annealing was studied. According to the variation of the microhardness values in ferrite and austenite with intercritical annealing time, austenite formation was classified into four stages: (a) austenite growth into pearlite at a slower rate than the ...

Enhanced mechanical properties of dual-phase steel by repetitive intercritical annealing
Canadian Metallurgical Quarterly, 2017ABSTRACTThe effect of repetitive intercritical annealing on the mechanical properties and work-hardening response of a typical C–Mn dual-phase (DP) steel was studied by consideration of different pre-intercritical annealing microstructures and martensite volume fractions.

Ferrite recrystallization and austenite formation in cold-rolled intercritically annealed steel
Metallurgical Transactions A, 1985The recrystallization of ferrite and austenite formation during intercritical annealing were studied in a 0.08C-1.45Mn-0.21Si steel by light and transmission electron microscopy. Normalized specimens were cold rolled 25 and 50 pct and annealed between 650 °C and 760 °C.

Phase-Field Modeling for Intercritical Annealing of a Dual-Phase Steel
Metallurgical and Materials Transactions A, 2014A phase-field model has been developed to describe microstructure evolution during intercritical annealing of a commercial DP600 dual-phase steel. The simulations emphasize the interaction between ferrite recrystallization and austenite formation from a cold-rolled pearlite/ferrite microstructure at high heating rates.

Mn Diffusion at Early Stage of Intercritical Annealing of 5Mn Steel
Journal of Iron and Steel Research International, 2015Mn distribution and austenite morphology at the early stage of intercritical annealing of 5Mn steel were investigated. It was experimentally demonstrated that a newly formed 20 nm-thick austenite was formed without the partitioning of Mn. The elemental analysis confirmed that the growth of austenite should be controlled by the diffusion of C prior to ...

Intercritical Annealing Response of Medium Manganese Steels Having Different Carbon Concentrations
steel research international, 2018Tensile properties of intercritically annealed medium Mn steels containing 4.5 wt% manganese and two different carbon levels of 0.1 and 0.2 wt% are predicted using a composite iso‐strain model. In the predictions, the evolutions of phase fraction and retained austenite stability with annealing temperature are considered assuming ortho‐equilibrium phase

Effect of intercritical annealing temperature on equilibrium between ferrite and austenite
Materials Science and Engineering, 1987Abstract The martensite content of the dual phase Fe-1.0%Mn-0.5%Cr-0.5%Si-0.2%C steel intercritically annealed for 20 min at temperatures up to 770 °C was the same as that calculated by partial equilibrium. This implies that partitioning of carbon occurs and not partitioning of substitutional solutes.
