Effect of Homogenizing Annealing on the Resistance of Welded Joints of Steel 15Kh11MFB to Brittle Fracture

  • Published:
Metal Science and Heat Treatment Aims and scope

Results of studies of structural changes in welded joints of steel 15Kh11MFB after homogenizing followed by heat refining are analyzed. It is shown that homogenizing at 1150°C lowers substantially the content of δ-ferrite in the structure of the steel and raises its ductile and plastic characteristics by more than a factor of 2 without changing the strength properties.
