TÉLÉCHARGEZ L’OFFRE

The present project aims developing better knowledge on the kinetics of nitrogen enrichment of grain oriented electrical steels, resulting in optimization of operational practices. This study will focus on characterizing the kinetics of oxidation and nitriding during the following process steps:

  • (i) decarburising,
  • (ii) nitriding
  • (iii) secondary recrystallization annealing.

It will include

  • microstructure studies leading to
  • optimization of thermochemical treatments
  • characterization of microstructures  at different steps of manufacturing
  • modelling of the kinetics of oxidation and nitriding
