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

Tailoring the deformation behaviour of a medium Mn steel through isothermal intercritical annealing [PDF]
Materialia, 2022 A novel concept of varying the strain hardening rate of a medium Mn steel with 8 wt\% Mn by varying the duration of the intercritical anneal after hot rolling was explored. It was found that the stability of the austenite phase showed an inverse square root relationship with intercritical annealing duration and that the maximum strain hardening rate ...

Tempering and Intercritical Annealing of Air‐Hardening 4 wt% Medium Manganese Steels
steel research international, 2021 The mechanical properties after tempering and intercritical annealing of medium manganese steels with 4 wt% Mn for forging applications are presented. After forging with subsequent air cooling, heat treatments were performed, specifically tempering from 250 and 450 °C and intercritical annealing between 600 and 675 °C.

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%)

Research on Hot Stamping-Carbon Partition-Intercritical Annealing Process of Medium Manganese Steel. [PDF]
Materials (Basel), 2023 In order to improve the plasticity of hot stamping parts, this paper combines the heat treatment process with the plastic forming of sheet metal, and creatively proposes a new process of hot stamping-carbon partitioning-intercritical annealing.

Internal Oxidation during Intercritical Annealing of CMnSi TRIP Steel
ISIJ International, 2009 The equilibrium internal oxidation of CMnSi TRIP steel at intercritical annealing temperatures in a +3°C dew point N2+10%H2 atmosphere was investigated by means of high resolution transmission electron microscopy of cross-sectional samples. The experimental conditions are considered to lead to the selective internal oxidation of Mn and Si.
