| Abstract: | The microstructure features and regularity of toughness of coarse grained HAZ ofpipeline steels in the welding process of first heat cycle,second heat cycle and postweld heattreatment were investigated systematically.On the basis of the dynamic fracture informationprovided by the instrumented charpy impact testing,some different criteria to evaluate duc-tile-brittle transition temperature were suggested. |
