Abstract
As part of a comprehensive evaluation of line-pipe steels, toughness measurements have been made by drop-weight-tear testing (DWTT) of commercial steels. Desulphurization and shape control of inclusions have been found to exert dramatic effects on toughness anisotropy and energy absorption. Without such controls, HAZ toughness can be vanishingly small.
The results of DWTT tests are combined with information from quantitative metallography and Charpy tests to illuminate the significance of inclusion control in improving dynamic toughness.
