SCC investigation of low alloy ultra-high strength steel

An interesting paper in « Chinese Journal of Aeronautics«  published on ScienceDirect.com.

The paper reports detail of investigation carried out. SCC behavior of low alloy ultra-high strength steel 30CrMnSiNi2A in neutral 3.5 wt%NaCl solution is investigated by SSRT with different strain rates under OCP, cathodic, and anodic polarization potentials, electrochemical measurements and surface analysis technique. The effect of strain rate on SCC behavior is analyzed and SCC mechanisms at OCP, cathodic and anodic polarization potentials are discussed in detail.

Failure Analysis – Industrial Case Studies

This web site deals with industrially-derived case studies in forensic engineering and failure analysis, which are firmly grounded in the context of their legal, insurance and design consequences. The development of this interactive learning package follows on from existing web-based projects in learning support via on-line tutorials, focussed internet resources and detailed analysis and discussion of case studies in failure.

Analysis of internal corrosion in subsea oil pipeline

A new interesting article in « Case Studies in Engineering Failure Analysis ».

Failure of a subsea crude oil API 5L X52 steel pipeline which led to oil leakage has been reported to occur after 27 years in service. Some leaks were found to form at the bottom of the horizontal API 5L X52 steel pipeline near an elbow section which connected the pipeline to a riser. The article present investigations to analyze the main cause of failure
