Tensile residual stresses at the surface are generally detrimental in terms of SCC, while compressive residual stresses (from shot peening or other processes) are beneficial. Under some circumstances, severe uniform cold working...

..., the metal readily absorbs hydrogen and oxygen. The hydride formation and the shallow surface embrittlement were indications of hydrogen and oxygen absorption. The oxygen absorbed at the surfaces created very hard and therefore brittle layers that made the tubes susceptible to cracking at ambient...

The high titanium-steel area ratio in the crevice could also promoted the hydrogen absorption of titanium. The brittle crack opening...
