... of the corrosion reaction, crack growth can occur by a hydrogen embrittlement process in much the same way as if hydrogen were in the gaseous form. A common feature of each of these processes is the subcritical crack growth in which cracks grow from existing flaws or initiation sites and grow to a size at which...
