Materials Science Aims and scope

Abstract

On the basis of the results of testing of influence of modifying microadditions (Ce, Y, Ba, Ca, and Zr) on the characteristics of the resistance to brittle fracture of a weld metal of welded joints of oil-and-gas pipelines, their optimal content in welds is determined. We propose mathematical models for numerical prediction of the crack resistance of welded joints.
