Abstract:

The phase composition and structure of defect portions of pipelines after long-term service in contact with a hydrogen sulfide-containing medium have been investigated. From structural changes, the process of the initiation of cracks and fracture of a low-carbon ferritic-pearlitic steel containing slag-induced laminations and precipitates of sulfides of the (Fe,Mn)S type has been reconstructed. The conditions under which a block cementite substructure is formed in the course of service and a transformation of the plate-type shape of the carbide phase occurs have been analyzed. It has been established that the dispersed carbides precipitating in this case limit the mobility of dislocations and thereby favor degradation of service properties of the pipe steel.
