[en] In this study, the roller pressure quench process is applied on a low-alloy steel plate with significant thickness. The aim is to obtain martensitic high strength steel without modifying the flatness. In order to optimize the process parameters, a finite element model is developed. The analysis couples the mechanical, thermal and metallurgical fields. This model provides results about the final microstructure, the residual stresses and the flatness at the end of the cooling process. It has been noticed that a two dimensional plane strain simulation is not accurate because it does not predict physical transversal residual stresses. A three dimensional simulation improves the results and enables to compute the thickness variation of the plate at the end of the quench process.
