SUSCEPTIBILITY OF 304 SS-Ti BIMETAL TO HYDROGEN INDUCED CRACKING

Popis výsledku v původním jazyce

The work deals with evaluation of hydrogen induced cracking of 304 SS-Ti bimetal after explosive bonding. 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 be also a potential position for hydrogenconcentration. After welding and exposition in corrosion solution bubbled with sulphide hydrogen the Ti of commercial purity and stainless steel 304 SS 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 OCTG. The work also includes ch
