Most of the models described above include measurements of microstructural elements such as ferritic grain size, interlamellar spacing, etc. Systematic measurement of these parameters can be carried out during test campaigns, but not in routine control. Systematic measurement of these parameters can be carried out during test campaigns, but not during routine inspection.

• The expression of these quantities as a function of process parameters, such as rolling temperatures and/or cooling rates, having been the subject of the studies cited in , properties can be expressed in terms of on-line measurements or parameters that can be calculated by process models. Microstructural dimensions are thus obtained indirectly, followed by on-line mechanical characteristics.

• The first...
