Advanced Non-Destructive Testing in Steels

Dear Colleagues,

Non-destructive testing (NDT) is a major issue for industrial and bio-medical applications, with several tens of billions USD in annual turnover. The technology in NDT is rapidly improving due to the development of new technologies, e.g., sensors, electronics, communications, software applications, and integration processes.

The NDT methods for steel applications are following this general trend. Year-by-year, the methods and processes become better and better, with the current state-of-the-art being the accurate detection of flaws and defects in steels in the order of microns.

The vision in steel production and manufacturing industry is the real time monitoring of the stress tensor distribution in steels, with the stress gradient components providing the metrics for steel failure prediction. Such an online measurement, in combination with the existing instruments monitoring flaws and defects in steels, can be the feedback tool for steel production and manufacturing lines, for optimizing the quality of steel products.

Apart from steel producers and manufacturers, the applications of stress gradient monitoring extend to the energy sector, concerning steel structures in both thermal and nuclear stations; the oil and gas industry piping systems and vessels under pressure; the transportation sector including shipping and ship industry as well as rails, trains, automobiles and finally in all different types of constructions involving steel.

The aim of this Special Issue is to present, on the one hand, the advances in non-destructive methods and instruments for steels in all aspects of steel production, manufacturing and use, and, on the other hand, the advances in the field of stress tensor distribution monitoring targeting the prediction of crack initiation and propagation.

The balanced contribution of both industry and academia in this Special Issue aspires to offer a comprehensive overview and roadmap in this hot industrial field.
