Abstract

The work deals with chosen properties of bimetal weld and its neighbourhood of Ti-clad Cr/Ni steel after one or double heat treatment (at 600 °C / 1.5 h / air) applied after explosive bonding. Notch impact strength values were compared with bimetal weld of C-Mn steel bonded with Ti after the same heat treatments. After double annealing, stainless steel Ti-clad showed the best transition temperature level (-60 °C at 310 J / cm2) unlike the Ti-clad C-Mn steel (-38 °C at 140 J / cm2). One annealing applied after explosive bonding resulted in worse parameters (decrease by 33 % and/or 87 % for stainless steel and/or C-Mn steel). Next part of work was target on sulphide stress cracking under tensile test and bent-beam test for Cr/Ni steel joined with Ti only after double heat treatment. Threshold level (for tensile) corresponded to 40 MPa and maximal deflection at 160 MPa to 0.609 mm without any defect. Results have been confronted with by now found facts.
