Abstract

The work deals with hydrogen susceptibility of joint of explosively welded anticorrosion steel of 18Cr/10Ni type with titanium of commercial purity. Studied welds were after twice heat treatment (600°C/1.5 h/air) and those were tested in corrosive solution in accord with NACE Standard TM0177-2003 (sulphide stress cracking under stress), representing dynamic test. Threshold level lay close to 40 MPa, approximately. The sources of failure were intermetallic phases of the Fe2Ti type detected using EBDS. Results were confronted with former results and accessible literature.

Keywords: 18/10-titanium weld, explosive welding, hydrogen susceptibility, intermetallic phase, EBDS
