Steel announces its failures years in advance. The announcement is written in the microstructure, and you do not have to cut the component to read it. AT A GLANCE The problem Creep, spheroidisation, sensitisation, graphitisation and hydrogen attack all mature quietly inside the microstructure long before there is any wall loss or crack for conventional NDT to find. By the time a flaw is detectable, most of the component's life is already spent. The technique In-situ metallogr
