Objectif
Cold rolled steel strip is often subjected to continuous annealing in a reactive atmosphere to achieve the required properties, while also ensuring appropriate states of surface cleanliness for subsequent treatment (e.g. phosphating, hot- dip galvanizing, etc.). Because the heat treatment cycle is very brief and the associated gas-metal reactions hardly achieve equilibrium, chemistry and property gradients can develop at the surface, which have up until now been considered an unavoidable drawback of the process. It is the objective of this project to investigate the possibilities of deliberately creating surface chemistry and property gradients by annealing in reactive atmospheres, with the aim of combining normally exclusive properties. This research programme will be specifically aimed at accumulating the necessary fundamental know-how to help create a new range of steel products. One of its constraints will be to maintain treatment conditions within the capabilities of existing processing lines, although minor modifications will obviously be necessary.
