Paper Number: ISOPE-P-90-133
... the notch toughness of the weld heat affected zone (HAZ) [6]. CF and TB are the reference steels. Both belong to the Si-Mn series; CF is low Mn steel and TB is low C steel. Photo. 1 shows the basemetal microstructures. PI and CT have fine proeutectoid ferrite (F) and bainite (Bu) microstructures. CF...

Paper presented at the The First ISOPE Pacific/Asia Offshore Mechanics Symposium, June 24–28, 1990
Paper Number: ISOPE-P-90-119
... ABSTRACT: The higher strength steels often show HEAT-AFFECTED ZONE (HAZ) softening. In the previous study, it was shown that CTOD toughness is much more important than strength matching to get higher welded joint performance in a stress concentrated region on the basis of the FEM analysis and...

Paper presented at the The First ISOPE Pacific/Asia Offshore Mechanics Symposium, June 24–28, 1990
Paper Number: ISOPE-P-90-120
... ABSTRACT: Influence of the local brittle zone on HAZ CTOD was discussed. From weld HAZ CTOD tests and simulated HAZ CTOD tests, it was clarified that the local brittle zone of a multi-pass weld HAZ is intercritically reheated coarse-grained zone, where high-carbon martensitic island was formed...
