abstract

A steel pipeline containing niobium, vanadium and titanium as microalloying elements was tested for hydrogen embrittlement. Hydrogenated specimens intercritically annealed at relatively low temperature to develop martensite islands in a ferrite matrix basically exhibited quasi-cleavage fracture with some ductile dimpling. The objective of this investigation, carried out by the principal investigator is to study the mechanical properties and susceptibility to hydrogen embrittlement effects on steel pipeline used for natural gas transport.
