... the fracture event, fracture morphologies and corresponding microstructures. It was also attempted to estimate the loads which might have been responsible for fracturing the joint. In addition, supporting tests and examinations were carried out on the materials, to assess the assembly against the original...

... suspension that was required for commissioning of subsea infrastructure. The tubing string separated below the tubing hanger in a 5-1/2 in (0.139 m) premium box connection. Examination of the failed alloy 725 box revealed a fracture morphology characteristic of hydrogen assisted cracking (HAC). The failure...

... to the corrosion potential (Ecorr) at room temperature. The affect of CP on the EAC susceptibility was evaluated as a function of the reduction in area and the time to failure. The fracture morphology was examined with scanning electron microscopy (SEM). The results indicate that an increase in the CP will enhance...

... CA 91330-8332, USA ABSTRACT Extensive research was conducted on prestressed ASTM A648 Class II steel wire to identify the fracture morphology. Hydrogen embrittlement results when this prestressed steel wire, embedded in concrete cylinder pipe, is cathodically overprotected. From this study...
