1 The fact that diffusible hydrogen embrittles is now widely recognised and forms the basis of many designs where the transport of hydrogen through the steel is impeded by introducing traps.2,3,4,5 e.g.) Hydrogen is present in minute quantities in steel,usually less than 1 part per million,but is attracted towards stress fields of the type associated with a crack tip.It therefore diffuses there,concentrates and thereby alters the fracture mechanism to the detriment of steel.
