Welcome message by Prof. Dr. Evangelos Hristoforou, the webinar Chair:

A method and the corresponding instruments, able to provide surface and bulk residual stress, as well as plastic deformation distribution monitoring in ferromagnetic steels and their welds, has been developed. The method is based on the correlation of the classic reference methods of stress tensor distribution determination and monitoring on the surface and the bulk of steels, namely X-ray Bragg–Brentano diffraction (XRD-BB) and neutron diffraction (ND), respectively, with the corresponding surface or bulk magnetic permeability and magnetostriction, resulting in reference magnetic stress calibration curves (MASC) for each different type of steel. The normalization of all different MASCs with respect to the corresponding yield point and maximum permeability, respectively, resulted in a universal law of dependence of stresses on magnetic properties concerning residual stresses, thus facilitating in determining the MASC of an unknown type of steel, only by a stress–strain characterization together with in situ magnetic permeability measurement. The mentioned uncertainty and speed of measurement for surface and bulk stress measurements have been verified for 17 out of the 42 different types of steel involved in the most interesting steel applications. The stress monitoring methods are also accompanied by localized stress rehabilitation, using localized induction heating probes. The system is accompanied by the proper software code, advancing the stress monitoring and rehabilitation method into an automated stress testing and rehabilitation system, meeting the needs for modern and advanced steel production and manufacturing.
