Tempering of Dual Phase steels: Microstructural evolutions and mechanical properties

Alexandre Mathevon, Véronique Massardier, Damien Fabrègue, Thierry Douillard et autres

Modelling the microstructural evolutions and mechanical properties during the tempering of Dual Phase steels is a key objective for industrials as this phenomenon has a strong impact on the final properties. After having determined the tempering kinetics of fully martensitic steels between …

Catalysts and Batteries Recycling to Produce Ferroalloys and High‐Speed Steel

Philippe Rocabois, Jean‐Pierre Dufour, Arnaud Dimet, Raphaël Baret et autres

To decrease its CO2 emission and environmental footprint, Erasteel produces its high‐speed steel using 90% recycled materials and targets to increase this ratio even further. The remaining 10% are mainly metallic oxides (V2O5, MoO3), ferroalloys (FeW, FeCr, FeSi), and cobalt. The total …

Automatic Pilot for Strip Processing Lines

Etienne MENIGAULT, Philippe Rocabois, Maxime Monnoyer, Arnaud Ollagnier et autres

ABSTRACT Today management of galvanizing lines is generally based on manual presets or individual models for each process without comprehensive optimization of quality and productivity. Fives developed a process control solution using predictive metallurgical models combining physical laws, artificial intelligence and machine …

Gibbs energy minimisation model for the austenite-ferrite phase transformation in Fe-C-X-Y alloys

Alexandre Mathevon, Michel Perez, Véronique Massardier, Damien Fabrègue et autres

A new model has been developed to predict austenite ↔ ferrite transformation kinetics in steels. For each alloying element, the concentration profile is computed solving a unique diffusion equation (including the 2 phases and the interface). The interface is described assuming linear …

Diffusion model for austenite formation kinetics during inter-critical annealing of dual-phase steels

Patrice Chantrenne, Michel Perez, Mélanie Ollat, Véronique Massardier et autres

Abstract A numerical solution for the ferrite-to-austenite phase transformation in a ternary iron alloy is proposed that predicts austenite formation during isothermal treatment. As the solution ensures perfect mass conservation of the solutes, it can be applied for long holding times until …

Non-metallic inclusion entrapment by slags: laboratory investigation

Philippe Rocabois, J. Lehmann, Christian GATELLIER, Jaume Terés

Non-metallic inclusions that originate from secondary metallurgy treatments may provoke nozzle clogging during continuous casting and lead more or less directly to surface defects on final products. The amount of these non-metallic inclusions (oxides or nitride) in the solid or liquid steel …

Comparative Study of the Influence of Homogeneous and Heterogeneous (Multi‐Phase) Precipitation Processes on the Particle Size Distribution

R. Aguiar, Hervé Muhr, Edouard Plasari, Marc Burty et autres

Abstract A Plexiglas vessel of a 0.30 m diameter filled with a diluted barium chloride solution and mixed by bubbling of an inert gas is used to model an industrial process. Solid sodium sulfate or sodium sulfate solution are added into the …
