Stress Corrosion Cracking (SCC) Mitigation

We perform Stress Corrosion Cracking (SCC) mitigation to ensure structural integrity of components.

Stress Corrosion Cracking typically occurs due to improper materials selection, heat treatment and unforeseen environmental conditions, i.e., inadequate maintenance, thermal transient conditions, or lack of consideration of residual stresses. It is one of the most common environmentally assisted failure modes encountered. Read more about SCC.

In considering the stress corrosion cracking problem in the heat affected zone of field welds in nuclear BWR primary pumping, the O’Donnell team developed a reliable mechanical stress improvement process which applies compressive stresses and is easy to control and verify.

Learn from the experience of others. Especially when one such “other” is Dr. William O’Donnell, PhD, PE, Founder and President of O’Donnell Consulting Engineers, Inc., and ASME “Engineer of the Year” – his 50 years of experience in analysis of components including fatigue and fracture safety evaluations and failure analyses are now comprised in this volume.

If you are interested learning more in Engineering Design, Manufacturing and Construction, as well as Failure Analysis, then this book is a must have!
