Study of Hydrogen Induced Cracking of Steel Welded with Titanium

Popis výsledku v původním jazyce

The work deals with evaluation of HIC of weld and its neighbourhood of stainless steel (18/10) and Ti of commercial purity realised explosively. Both joined materials individually show a good resistance against hydrogen embrittlement. For bonded materials sinusoidal interface with curls is typical. In curls and in their vicinity intermetallic phases are often detected. Those represent hard and simultaneously more brittle areas which can be sensitive to hydrogen induced cracking. The bonding line can bealso a potential position for hydrogen concentration. After welding and exposition in corrosion solution bubbled with sulphide hydrogen the titanium and stainless steel showed numerous thin cracks detected right in the intermetallic phases. The total crack sensitivity ratio (CSR), crack length ratio (CLR) and crack thickness ratio (CTR) were evaluated according the NACE Standard TM0284 item No. 21215. The results were confronted with the Specification 5L ANSI/API valid for oil country tu
