Micrography of the weld metal of the pipe to the fitting. It is possible to see columnar grains and recristalized grains. In the same way, the yellow/white is the austenite and the blue/red is the ferite.

Vibration Induced Fatigue in a SS Oil Piping
M - Duplex Stainless SteelP - PipingAp - FPSOCd - Vibration Induced Fatigue
Cm - NaOH Electrolytic Etched MicroDf - Weld Metal
Cap pass in the weld metal, presenting a large amount of delta ferrite (retained) due to a probable quick cool of the pool during welding (since this pass is too thin, perhaps a remelting). Although it is not good to present this microstructure, it did not affect the failure.
