钢的延迟失效现象与电解引入的氢的存在有关。延迟失效可能发生在较宽的相对较低的施加应力范围内，并且该应力范围取决于强度水平、缺口锐度和引入氢气后的时效时间。观察到的延展性降低是氢渗透深度和氢脆程度或严重程度的函数。带负载和不带负载时效的影响表明，在氢存在下超过某些最小临界应力会使钢脆化。贝氏体结构的行为方式与回火马氏体相似，只是整体脆化似乎不太严重。对于指挥官：
The phenomenon of delayed failure in steel has been correlated with the presence of electrolytically introduced hydrogen. Delayed failure may occur over a wide range of relatively low applied stresses and this stress range is dependent upon strength level, notch acuity and aging time after the introduction of hydrogen. The observed reductions in ductility are a function of both the depth of hydrogen penetration and the degree or severity of hydrogen embrittlement. The effects of aging with and without load have demonstrated the necessity of exceeding some minimum critical stress in the presence of hydrogen to embrittle steel. A bainitic structure was shown to behave in a fashion similar to that of tempered martensite, except that the overall embrittlement appeared less severe. FOR THE COMMANDER:
