Simulation of intercritical annealing in low-alloy TRIP steels

Steel Research, 2000
A coupled thermodynamic/kinetic calculation of austenite formation during intercritical annealing of low-alloy TRIP steels is presented. The simulation was performed with the use of Dictra computational kinetics software, which employs a procedure for the numerical solution of the coupled diffusion equations involved, as well as mobility databases for ...

Dilatometric Analysis of Austenite Formation during Intercritical Annealing

Metals and Materials International, 2008
Dilatometry is a useful method to investigate the transformation kinetics of ferrous alloys. In the present study, a dilatometric analysis procedure that considers the effect of non-isotropic volume change was applied to evaluate the kinetics of austenite formation during the intercritical annealing of TRIP steels. Metallographic analysis was conducted

Extra work hardening in room-temperature quenching and partitioning medium Mn steel enabled by intercritical annealing

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2020
The present work applies an intercritical annealing process on a room-temperature quenching and partitioning (RT Q&P) medium Mn steel. It is found that the intercritical annealing maintains the amount of austenite while improves its mechanical stability.
