Metallographie and X-ray diffraction investigations as well as microprobe sampling were performed on the samples. Mechanical orientation of particles caused by plastic deformation and carbide scattering has been observed. The diffusion behaviour has been investigated for the elements Cr, Ni, Mn, and Si, respectively. The existence of (Cr,Fe) 7C3 carbides in the welding region was also observed. © Carl Hanser Vpriai' GmhH & Co. KG.Article10.3139/120.110568
