An indentation based investigation on the characteristics of artificially aged pipeline steels

摘要

The decay of the mechanical properties of structural components operating in an aggressive environment can be detected by non-destructive indentation tests. The effectiveness of this approach has been verified on artificially aged pipeline steel. Indentation tests have been performed at different scales to verify the transferability of the laboratory results to the field conditions, in view of the possible development of in-situ diagnostic procedures.
