Influence of boron addition on microstructure and mechanical properties of medium-Mn advanced high-strength steel

Journal of Materials Research and Technology
This study investigates the effects of 0.12 wt% boron addition on the microstructure and mechanical properties of a Fe-0.08C-4.5Mn-2.5Cr–1Si medium-Mn steel in as-rolled conditions and after the intercritical annealing process.

Role of refined martensite microstructure and intercritical Mn partitioning on austenite reversion in Fe–5Mn-1.5Al-0.2C alloy

Journal of Materials Research and Technology
In this paper, we demonstrate a novel design to accelerate the austenite reversion of a Fe–5Mn-1.5Al-0.2C (wt.%) medium Mn steel (MMS), via a deliberating adding an elevated pre-annealing before conventional intercritical annealing.

Crystallography and mechanical properties of intercritically annealed quench and partitioned high-aluminum steel

Materials Characterization, 2019
Abstract The quenching and partitioning response of intercritically annealed steel with aluminum contents in the 2–3 wt.% range and a carbon content of 0.2 wt.% was studied. Two types of morphologies for retained austenite were observed in electron backscatter diffraction studies: blocky, untransformed austenite grains and partially transformed ...

Phase transformations in low-carbon manganese steel 6Mn16 [PDF]

Metalurgija, 2009
The kinetics of phase transformations of the austenite of 6Mn16 steel during continuous cooling are presented in a CCT diagram. Manganese partitioning between ferrite and austenite during intercritical annealing is enhanced by prior soft annealing.

Quantitative Analysis on Carbide Precipitation in V-Ti Microalloyed TRIP Steel Containing Aluminum

MATEC Web of Conferences, 2016
Introducing fine precipitates is an important way to enhance the properties of transformation-induced plasticity (TRIP) steels. In present work, two V-Ti microalloyed TRIP steels containing aluminum with different content were compared. The average size,
