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

摘要

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 1150A degrees C lowers substantially the content of delta-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.
