Splitting susceptibility in modern X80 pipeline steels

Materials Science and Engineering: A, 2020
Abstract The microstructure and crystallographic texture of modern industrially produced API X80 grade pipeline steels were studied to identify the factors associated with the phenomenon known as splitting, which can occur on the fracture surfaces of Charpy, drop-weight tear test and full-scale fracture propagation tests.

Quantification of Splitting in X80 Pipeline Steel

Volume 3: Operations, Monitoring, and Maintenance; Materials and Joining, 2018
The results of in-depth analysis of microstructure and crystallographic texture of several industrial batches of line pipes with known full-scale burst test results are presented. Several microstructural features promoting splitting are highlighted and quantified using electron back-scattered diffraction (EBSD) data.
