Abstract
The work deals with multilayer welds made with Inconel 52 wire, which have a high sensitivity to formation of hot ductility dip cracks in the heat-affected zone, and welds made with 52MSS wire, which turned out to be insensitive to formation of this type of cracks at a certain level of strain rates. Changes of structural characteristics of welds made with the above wires were studied by the methods of transmission microscopy, X-ray microprobe analysis, microhardness measurement, as well as electron backscatter diffraction. 9 Ref., 2 Tables, 8 Figures.
 
Keywords: multilayer surfacing, ductility dip cracks, nickel alloys, dislocation density, stacking fault energy, microhardness
