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.

Journal of Materials Research and Technology, 2020 Conventional spheroidization heat treatments of bearing steels are long-term, therefore it is necessary to study alternatives to decrease the heat treatment time to save energy consumption. This work aimed to develop a new manufacturing route in order to

Transformations during Intercritical Annealing of a TRIP-assisted Steel.
ISIJ International, 1998 During intercritical annealing of cold rolled TRIP-assisted steel, ferrite matrix recrystallizes and austenite forms. After subsequent quenching, part of that austenite may remain at room temperature as retained austenite, while the other part transforms into martensite. Based on their respective origin, recrystallized ferrite grains were recognized as

New Multiphase CP and DP 1000 MPa strength level grades for improved performance after hot forming [PDF]
, 2019 Pure martensitic steels have after hot forming limited performance in terms of rest ductility which limits the application in crash relevant parts. New steel grades were designed in the EU project HOTFORM including the corresponding process routes. These

Mechanisms of austenite growth during intercritical annealing in medium manganese steels
Scripta Materialia, 2022 Abstract 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 ≤ 0.5Tmelt, where the bulk diffusion of Mn is extremely slow.
