The screw failed was revealed to have failed through a fatigue mechanism by the presence of striations in the scanning electron micrograph. The crack in the plate was revealed to have originated at the upper, outer corner of the plate...

The parts were required to be electrolytically cadmium-plated in accordance with QQ-P-416E Type II, Class 2, and a post-bake at 190°C (375°F) was specified to prevent hydrogen embrittlement. A 100% magnetic...

..., this mechanism was ruled out. Liquid metal embrittlement is caused by penetration of a liquid metal into the base metal, usually at the grain boundary. Penetration of steel by molten tin, which was plated onto the coupling, is an example of LME. Because LME is an unusual form of attack in oilfield service...
