Charpy V-notch (CVN) impact
tests are the most widely used method for characterizing material toughness in
steel applications. While the CVN method is both cost-effective and efficient,
CVN data is limited when it comes to performing fitness-for-service or
remaining-life calculations. Correlated data between Charpy and other fracture
tests are used together for these purposes, but this is also a limited
solution, especially in modern steel applications.

EWI has developed as assessment
method that can characterize the ductile-to-brittle temperature transition
behavior for structural steels more reliably than other existing methods. The
approach can be applied to a wide range of modern steels including structural
pipeline and marine materials.

Bill Mohr, Principal
Engineer for Structural Integrity, has written a new paper, Scatter in Charpy Data Considered as a
Transferrable Parameter
, to discuss this new scatter assessment method and its
future applications.
