Summary: | The influence for the upper transition temperature of toughness in the weld area is the transformation of coarse grained austenite to upper bainite. The supposition can be tested with the measurements of toughness for the potentially the most brittle microstructures in the heat affected zone (HAZ) of the weld. Reliable data about connection between the microstructure and toughness is available only for the microstructures where they are formating at transformation at cooling for normalisation, and at cooling of structural steels at hot rolling. Set of tests has been done to determine if it is possible to achieve requested microstructures. |
