Decrease in structural heterogeneity of incomplete refining region of the HAZ of elded joints in pearlitic steels
V.V. Dmitrik, A.N. Pashchenko
Ukrainian Engineering Academy, Kharkiv, UkraineAbstract
Intensity of initiation and development of damage at creep of welded joints in heat-resistant steels is shown to depend upon the kind of initial metal structure in incomplete refining region. Control of temperature conditions of the latter can provide improvement of operational reliability of welded joints.
Keywords: automatic welding, pearlitic steels, welded joints, microdamage, initial structure, structural heterogeneity, steam pipelines
