Austenite formation and cementite dissolution during intercritical annealing of a medium-manganese steel from a martensitic condition

Materials & Design, 2021
In the present study, in situ high-energy X-ray diffraction (HEXRD), dilatometry, and metallography were conducted for the purpose of understanding microstructure evolution during intercritical annealing of a Fe-0.19C-4.39Mn steel from a martensitic ...

Effect of intercritical annealing on the mechanical properties of dual-phase steel [PDF]

Ironmaking & Steelmaking, 2022
A dual-phase steel chemistry has been processed with varying intercritical annealing temperatures and the properties investigated. It was found that increasing the temperature in the intercritical region led to an increase in the volume fraction (52%–65%)

Effects of different intercritical annealing processes on microstructure and cryogenic toughness of newly designed medium-Mn and low-Ni steel

Journal of Materials Research and Technology, 2023
Through the idea of replacing Ni with Mn, a shortened process of ultra-fast cooling and two-step intercritical annealing for medium-Mn and low-Ni steel after rolling was designed.

Effect of Cooling Practice on the Mechanical Properties of Medium‐Manganese Aluminum‐Alloyed Steels after Intercritical Annealing Quench and Partition Treatment

steel research international, Volume 96, Issue 2, February 2025.
Two medium (3 wt%)‐manganese aluminum steels are subjected to three different cooling strategies after hot rolling. The steels experience intercritical annealing quench and partition treatments subsequent to hot rolling and cooling. The results show that it is possible to enhance strength and elongation by changing the thermomechanical process and heat‐

Alternative Approach for the Intercritical Annealing of (Cr, Mo, V)-Alloyed TRIP-Assisted Steel before Austempering

Metals, 2022
TRIP-assisted C-Si-Mn steels are usually subjected to austempering with a preliminary intercritical annealing that is targeted at the multi-phase structure with 40–60 vol.% of proeutectoid ferrite.

Mechanisms of austenite growth during intercritical annealing in medium manganese steels

Scripta Materialia, 2022
The third-generation advanced high strength medium manganese (3–12 wt.%) steels typically consist of ultrafine-grained dual-phase (austenite-ferrite) microstructure, obtained through the intercritical annealing of martensite at temperatures typically ...

Accelerated Ferrite-to-Austenite Transformation During Intercritical Annealing of Medium-Manganese Steels Due to Cold-Rolling

Metals, 2019
Prior cold deformation is known to influence the ferrite-to-austenite (α → γ) transformation in medium-manganese (Mn) steels that occurs during intercritical annealing.
