Electromagnetic and micro-magnetic non-destructive characterization (NDC) for material mechanical property determination and prediction in steel industry and in lifetime extension strategies of NPP steel components
Nondestructive Characterization (NDC) of materials is a technology of increasing application by industrial users for process monitoring and control as well as in predictive maintenance procedures integrated in plant lifetime management systems. The main reason for this fact in materials processing is the need for a better process understanding and mastering in oder to produce quality according to a zero-defect-principle and the objective to reduce non-conformities compared with a given quality specification. This means: Integration of NDC by use of intelligent sensors into monitoring and control systems to predict mechanic properties and to detect and document their discontinuities. For lifetime management of components in plants NDC in asked for to support lifetime prediction procedures, which have to be observed if lifetime extension is an objective to reduce costs.
