METHOD FOR CONTINUOUSLY EVALUATING MECHANICAL AND MICROSTRUCTURAL PROPERTIES OF A METALLIC MATERIAL, IN PARTICULAR A STEEL, IN A COLD DEFORMATION PROCESS AND RELATED APPARATUS
A method is described for continuously evaluating mechanical and microstructural properties of a rolled metallic material (L) in a cold deformation process, subjected to combinations of deformation forces selected among compression forces, traction forces and bending moment applied at low deformation speed in a range comprised between 1*10-4 and 10*10-4 s-1 which corresponds to laboratory static conditions and at high deformation speed in a range comprised between 0.1 and 10 s-1 which corresponds to dynamic conditions, the method comprising the step of: - measuring characteristic parameters of the cold deformation process under dynamic conditions, comprising at least one value of temperature (T), deformation (ε) and deformation speed (έ) of the rolled sheet (L); characterized in that it further comprises the steps of: - calculating the traction yield strength at high deformation speed (σYD) according to equation (I), being: σc a compression strength of the rolled sheet (L) when a compression force (Fc) is
